In the course of an immune response, antibodies undergo affinity maturation in order to increase their efficiency in neutralizing foreign invaders. Affinity maturation occurs by the introduction of multiple point mutations in the variable region gene that encodes the antigen binding site. This somatic hypermutation is restricted to immunoglobulin genes and occurs at very high rates. The precise molecular basis of this process remains obscure. However, recent studies using a variety of in vivo and in vitro systems have (...) revealed important regulatory regions, base motifs that are preferred targets of mutation and evidence that transcription may play an active role in hypermutation.

One of the fundamental questions of life sciences is one of whether there are genuinely random biological processes. An affirmative or negative answer to this question may have important methodological consequences. It appears that a number of biological processes are explicitly classified as random. One of them is the so-called somatic hypermutation. However, closer analysis of somatic hypermutation reveals that it is not a genuinely random process. Somatic hypermutation is called random because the exact (...) outcome of this process is difficult to predict in practice. The case of somatic hypermutation suggests that there may be no scientific evidence of a single case of ontologically random process in the biological world. (shrink)

Base pair mismatches in DNA arise from errors in DNA replication, recombination, and biochemical modification of bases. Mismatches are inherently transient. They are resolved passively by DNA replication, or actively by enzymatic removal and resynthesis of one of the bases. The first step in removal is recognition of strand discontinuity by one of the MutS proteins. Mismatches arising from errors in DNA replication are repaired in favor of the base on the template strand, but other mismatches trigger base excision or (...) nucleotide excision repair (NER), or non‐repair pathways such as hypermutation, cell cycle arrest, or apoptosis. We argue that MutL homologues play a key role in determining biologic outcome by recruiting and/or activating effector proteins in response to lesion recognition by MutS. We suggest that the process is regulated by conformational changes in MutL caused by cycles of ATP binding and hydrolysis, and by physiologic changes which influence effector availability. (shrink)

Soma‐to‐germline feedback is forbidden under the neo‐Darwinian paradigm. Nevertheless, there is a growing realization it occurs frequently in immunoglobulin (Ig) variable (V) region genes. This is a surprising development. It arises from a most unlikely source in light of the exposure of co‐author EJS to the haplotype data of RL Dawkins and others on the polymorphism of the Major Histocompatibility Complex, which is generally assumed to be the most polymorphic region in the genome (spanning ∼4 Mb). The comparison between the (...) magnitude of MHC polymorphism with estimates for the human heavy chain immunoglobulin V locus (spanning ∼1 Mb), suggests IGHV could be many orders of magnitude more polymorphic than the MHC. This conclusion needs airing in the literature as it implies generational churn and soma‐to‐germline gene feedback. Pedigree‐based experimental strategies to resolve the IGHV issue are outlined.

Somatic diversification of antigen receptor genes depends on the activity of enzymes whose homologs participate in a mutagenic DNA repair in unicellular species. Indeed, by engaging error-prone polymerases, gap filling molecules and altered mismatch repair pathways, lymphocytes utilize conserved components of genomic stress response systems, which can already be found in bacteria and archaea. These ancient systems of mutagenesis and repair act to increase phenotypic diversity of microbial cell populations and operate to enhance their ability to produce fit variants (...) during stress. Coopted by lymphocytes, the ancient mutagenic processing systems retained their diversification functions instilling the adaptive immune cells with enhanced evolvability and defensive capacity to resist infection and damage. As reviewed here, the ubiquity and conserved character of specialized variation-generating mechanisms from bacteria to lymphocytes highlight the importance of these mechanisms for evolution of life in general.

Targeted hypermutation has proven to be a useful survival strategy for bacteria under severe stress and is also used by multicellular organisms in specific instances such as the mammalian immune system. This might appear surprising, given the generally observed deleterious effects of poor replication fidelity/high mutation rate. A previous theoretical model designed to explore the role of replication fidelity in the origin of life was applied to a simulated hypermutation scenario. The results confirmed that the same model is (...) useful for analyzing hypermutation and can predict the effects of the same parameters (survival probability, replication fidelity, mutation effect, and others) on the survival of cellular populations undergoing hypermutation as a result of severe stress.

This article considers scientific data and methods taken as a vocabulary for a visual language of poetics, shaping an artistic practice exploring the liminal poetics of space, time, science and mythology, equally considered. These artworks focus on the moving image as an immersive, architectonic construct, one that makes it possible to blur the boundary between space and time. They are cinematic environments that create a space of spatial and temporal ambiguity, open to the performative role of the viewer in composing (...) the unfolding narrative. The artworks presented here began in the crossover between art and science, technology and anthropology, exploring topics and incorporating methods from each area. Transdisciplinary processes play a critical role in this artistic research. These works reflect cinema approached as a multimodal field of possibilities in which montage motivates movement and focus through this field, creating a participatory composition of sight, sound, movement and memory that immerses viewers by actuating somatic perception. Shape, scale, immersion, interactivity, simultaneity, embodiment, implementation and the manipulation of time create concrete metaphors that echo the multivalent content of the works: a collaboration with 300 tropical spiders to create a Kino, then letting the audience walk freely among them (or the spiders freely among the audience); an immersive environment enacting the space-time of glacial ice to experience the time of a different form of matter as somatosensory experience; a journey through the human history of the Moon, transcending time, political ideologies, realities and cultures as an encompassing field of simultaneous views and sounds; performing a 2000-year-old act of Thessalian magic on the skyline of Hong Kong. Combining the technological tools available to cinema and science, contrasting magnifications and speeds of observation reveal a material poetics beyond appearance. The artworks presented here elaborate the details of cardinal subjects, diving deep into fundamental domains to unravel the cultural implications embedded within the aesthetics of their data artefacts.

Quantitative somatic phenomenology, a technique based in part on little-articulated practices in the field of somatics, is offered as an embodied phenomenological method of defining, operationalizing and controlling for state of consciousness in terms of the size, shape, location and dynamic movement of specific qualitative phenomena relative to the body. This approach offers a possible beginning point for the needed task of controlling for state of consciousness as a variable in each and every method of inquiry, including standard science. (...) It also may assist methods such as neurophenomenology by offering the prospect of a more accurate and pragmatic standardized praxis. Potential approaches to scientific validation are explored.

This study investigated the performance of boys with psychopathic tendencies and comparison boys, aged 9 to 17 years, on two tasks believed to be sensitive to amygdala and orbitofrontal cortex func- tioning. Fifty-one boys were divided into two groups according to the Psychopathy Screening Device (PSD, P. J. Frick & R. D. Hare, in press) and presented with two tasks. The tasks were the gambling task (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) and the Intradimensional/ (...) Extradimensional (ID/ED) shift task (R. Dias, T. W. Robbins, & A. C. Roberts, 1996). The boys with psychopathic tendencies showed impaired performance on the gambling task. However, there were no group differences on the ID/ED task either for response reversal or extradimensional set shifting. The implications of these results for models of psychopathy are discussed.

The somatic mutation theory has been the prevailing paradigm in cancer research for the last 50 years. Its premises are: (1) cancer is derived from a single somatic cell that has accumulated multiple DNA mutations, (2) the default state of cell proliferation in metazoa is quiescence, and (3) cancer is a disease of cell proliferation caused by mutations in genes that control proliferation and the cell cycle. From this compelling simplicity, an increasingly complicated picture has emerged as more (...) than 100 oncogenes and 30 tumor suppressor genes have been identified. To accommodate this complexity, additional ad hoc explanations have been postulated. After a critical review of the data gathered from this perspective, an alternative research program has been proposed. It is based on the tissue organization field theory, the premises of which are that carcinogenesis represents a problem of tissue organization, comparable to organogenesis, and that proliferation is the default state of all cells. The merits of these competing theories are evaluated herein. BioEssays 26:1097–1107, 2004. © 2004 Wiley Periodicals, Inc. (shrink)

The deep influence of affectivity on learning is now widely acknowledged (Keefer et al., 2018; Sánchez-Álvarez et al., 2021). For instance, it has been shown that affect influences key learning-relevant processes, such as motivation, perception, behavior, and critical thinking (Izard, 2002; Mayer & Salovey, 1997). Evidence also shows that emotion and mood strongly influence attention, which in turn drives learning and memory (Elbertson et al., 2010; Elias et al., 1997). Intersubjective phenomena, such as the degree of affection and respect between (...) child and teacher, also affect the child’s learning processes, academic outcomes, and brain development (Kusché & Greenberg, 2006; Ryan & Patrick, 2001). However, the relevant literature is not paying attention to increasing evidence showing that affective phenomena are rooted in interoceptive and homeostatic self- and co-regulatory processes within and between people’s living bodies (Barrett, 2017; Carvalho & Damasio, 2021; Craig, 2015, 2018; Fotopoulou et al., 2022; Fotopoulou & Tsakiris, 2017; Seth & Friston, 2016). In this theoretical chapter, we explore this connection and its importance for learning. We argue that affective experience plays a fundamental role in learning, and that affective experience is rooted in the homeostatic self-/co-regulation of living bodies. Therefore, the homeostatic self-/co-regulation of living bodies plays a fundamental role in learning. In other words, there is an intra- and interpersonal somatic dimension of learning that demands explicit consideration in educational contexts. In this way, we aim to contribute to an understanding of learning and education that moves away from an individualistic, brain-centered information-processing conception toward one centered on sentient, interdependent living bodies.

Although movement has long been recognized as expressing emotion and as an agent of change for emotional state, there was a dearth of scientific evidence specifying which aspects of movement influence specific emotions. The recent identification of clusters of Laban movement components which elicit and enhance the basic emotions of anger, fear, sadness and happiness indicates which types of movements can affect these emotions (Shafir et al., 2016), but not how best to apply this knowledge. This perspective paper lays out (...) a conceptual groundwork for how to effectively use these new findings to support emotional resiliency through voluntary choice of one’s posture and movements. We suggest that three theoretical principles from Laban Movement Analysis (LMA) can guide the gradual change in movement components in one’s daily movements to somatically support shift in affective state: (A) Introduce new movement components in developmental order; (B) Use LMA affinities-among-components to guide the expansion of expressive movement range and (C) Sequence change among components based on Laban’s Space Harmony theory to support the gradual integration of that new range. The methods postulated in this article have potential to foster resiliency and provide resources for self-efficacy by expanding our capacity to adapt emotionally to challenges through modulating our movement responses.

An understanding of the factors behind the evolution of multicellularity is one of today’s frontiers in evolutionary biology. This is because multicellular organisms are made of one subset of cells with the capacity to transmit genes to the next generation and another subset responsible for maintaining the functionality of the organism, but incapable of transmitting genes to the next generation. The question arises: why do somatic cells sacrifice their lives for the sake of germline cells? How is germ/soma separation (...) maintained? One conventional answer refers to inclusive fitness theory, according to which somatic cells sacrifice themselves altruistically, because in so doing they enhance the transmission of their genes by virtue of their genetic relatedness to germline cells. In the present article we will argue that this explanation ignores the key role of policing mechanisms in maintaining the germ/soma divide. Based on the pervasiveness of the latter, we argue that the role of altruistic mechanisms in the evolution of multicellularity is limited and that our understanding of this evolution must be enriched through the consideration of coercion mechanisms.

This chapter presents emotion as a function of brain-body interaction, as a vital part of a multi-tiered phylogenetic set of neural mechanisms, evoked by both instinctive processes and learned appraisal systems, and argues to establish the primacy of emotion in relation to cognition.

SAMA identifies quintessential components, facets, and (...) functions of affect necessary to provide a new domain, namely educational neuroscience, with a basis on which to build a dynamic model of affect serving to critique traditional cognitivist-oriented curricula and instruction, and to inform an alternative: neuropedagogy.

One important function of emotions is to guide decision making and behaviors for survival in complex environments. In the context of such reasoning, the somatic marker hypothesis (Damasio, 1994) has argued that bodily states are represented in specific brain regions, such as the insula, and would play critical roles in decision making. However, it still remains unclear what causal roles bodily states would play in decision making, and how the bodily states would change accompanying decision making. Thus, the aim (...) of this article is to reconsider aspects of the brain and bodily states in decision making based on recent findings. Questions for future research are proposed based on such findings. (shrink)

The somatic integration definition of life is familiar from the debate on the determination of death, with some bioethicists arguing that it supports brain death while others argue that some brain‐dead bodies exhibit sufficient somatic integration for biological life. I argue that on either interpretation, the somatic integration definition of life implies that neither the preimplantation embryo nor the postimplantation embryo meet the somatic integration threshold condition for organismal human life. The earliest point at which a (...) somatic integration determination of life could be made would be the beginning of the fetal stage, 9 weeks postfertilization. Bioethical implications are considered, specifically with respect to the moral status of the postimplantation embryo in embryo research and abortion. (shrink)

Reprogramming of somatic cells to a pluripotent state holds huge potentials for regenerative medicine. However, a debate over which method is better, somatic cell nuclear transfer (SCNT) or induced pluripotent stem (iPS) cells, still persists. Both approaches have the potential to generate patient‐specific pluripotent stem cells for replacement therapy. Yet, although SCNT has been successfully applied in various vertebrates, no human pluripotent stem cells have been generated by SCNT due to technical, legal and ethical difficulties. On the other (...) hand, human iPS cell lines have been reported from both healthy and diseased individuals. A recent study reported the generation of triploid human pluripotent stem cells by transferring somatic nuclei into oocytes, a variant form of SCNT. In this essay, we discuss this progress and the potentials of these two reprogramming approaches for regenerative medicine. (shrink)

Damasio's somatic marker hypothesis (SMH) is a prominent neuroscientific hypothesis about the mechanisms implementing decision-making. This paper argues that, since its inception, the SMH has not been clearly formulated. It is possible to identify at least two different hypotheses, which make different predictions: SMH-G, which claims that somatic states generally implement preferences and are needed to make a decision; and SMH-S, which specifically claims that somatic states assist decision-making by anticipating the long-term outcomes of available options. This (...) paper also argues that neither hypothesis is adequately supported empirically; the task originally proposed to test SMH is not a good test for SMH-S, and its results do not support SMH-G either. In addition, it is not clear how SMH-G could be empirically invalidated, given its general formulation. Suggestions are made that could help provide evidence for SMH-S, and make SMH-G more specific. 1 Introduction 2 Two Hypotheses: Somatic Markers as Embodied Preferences, and as a Source of Farsightedness 3 Lack of Evidence for Somatic Farsightedness 4 Does Making Decisions Require Somatic Markers, and can it be Shown in the Laboratory? 5 Conclusion CiteULike Connotea Del.icio.us What's this?

A widely accepted tenet of evolutionary biology is that spontaneous mutations occur randomly with regard to their fitness effect. However, since the mutation rate varies along a genome and this variation can be subject to selection, organisms might evolve lower mutation rates at loci where mutations are most deleterious or increased rates where mutations are most needed. In fact, mechanisms of targeted hypermutation are known in organisms ranging from bacteria to humans. Here we review the main forces driving the (...) evolution of local mutation rates and identify the main limiting factors. Both targeted hyper‐ and hypomutation can evolve, although the former is restricted to loci under very frequent positive selection and the latter is severely limited by genetic drift. Nevertheless, we show how an association of repair with transcription or chromatin‐associated proteins could overcome the drift limit and lead to non‐random hypomutation along the genome in most organisms.Editor's suggested further reading in BioEssays Stress‐induced mutation via DNA breaks in Escherichia coli: A molecular mechanism with implications for evolution and medicine Abstract.

Purpose. The main purpose of the article is the analysis of the phenomenon and manifestations of the somatic transformations in the context of anthropo-technological evolution at the beginning of the XXI century. Theoretical basis. The author determines the understanding of the concept "somatic transformations" in the frames of anthropotechnogynesis is possible only on the base of integrative approach and combination of post-non-classical scientific paradigm methodology, theory of the technological development, ideas of trans-humanism, informative society concepts, and net technologies (...) influence on the identity of the human being with robots in the sphere of bioethics and nanoethics, the ethics of new technologies and legal documents which are regulating the processes of technotransformation of the human being. Originality. The author has proved on the example of analysis of the somatic transformations own psychosomatics as he solves some important global in the context of anthropotechnogynesis that a person with help of technological enlargement of and branch problems, so he is trapped of alienation in the very crucial stage, loses the identity and crashes the corporeality in his self. Conclusions. As evidenced by the given analysis, at the modern stage the anthropotechnogynesis is followed by the large-scale quantitative and qualitative somatic transformations based on NBIC-convergence, as a result, a new anthropological subspecies – Homo technologicus appears. All these transformations are a regular stage of evolution, which confirms the thesis of the essential and functional connection of technology with the human body, which are in a relationship of "mutual provocation". In the base of the paradigmatic ontological and anthropological shift which has been on the modern stage, lies the idea of continuity of anthropotechnological co-evolution of the human body and its environment which projects itself in psychosomatic human structure, making a transformation program for better adaptation in technonanobeing. The convergence of human life and techno-existence is a platform for somatic transformations. They are divided into two main groups: intra-structural, substantial, related to techno-modification of the human body directly through biotechnology and genetic engineering, cyborgization, xenotransplantation, Hi-Hume connection with Hi-Tech and others, and external-contextual, when under the influence of pancommunication and hybridization the environment is increasingly mentalized and somatized, and modern technologies are gradually transformed into the social body of man.

Muselmannwas a term used in German concentration camps to describe prisoners near death due to exhaustion, starvation, and helplessness. This paper suggests that the inhuman conditions in the concentration camps resulted in the development of a defensive sense of disownership toward the entire body. The body, in such cases, is reduced to a pure object. However, in the case of theMuselmannthis body-as-object is felt to belong to the captors, and as such is therefore identified as a tool to inflict suffering (...) and pain on theMuselmannhimself. In this situation, lacking cognitive resources, theMuselmannmay have no other alternative than to treat his body as an enemy, and then to retreat or disinvest from the body. This response is a form of somatic apathy, an indifference that is tied to a loss of the self/non-self distinction. This may, in turn, lead to suicidal inclinations, even after liberation from the camp. (shrink)

The essays in this volume all ask what it means for human beings to be embodied as desiring creatures—and perhaps still more piercingly, what it means for a philosopher to be embodied. In taking up this challenge via phenomenology, psychoanalysis, hermeneutics, and the philosophy of literature, the volume questions the orthodoxies not only of Western metaphysics but even of the phenomenological tradition itself. We miss much that has philosophical import when we exclude the somatic aspects of human life, and (...) it is therefore the philosopher’s duty now to rediscover the meaning inherent in desire, emotion, and passion—without letting the biases of any tradition determine in advance the meaning that reveals itself in embodied desire. Continental philosophers have already done much to challenge binary oppositions, and this volume sets out a new challenge: we must now also question the dichotomy between being at home and being alienated. Alterity is not simply something out there, separate from myself; rather, it penetrates me through and through, even in my corporeal experience. My body is both my own and other; I am other than myself and therefore other than my body. Additionally, this book is a conversation, not a presentation of a new orthodoxy. Thus, the hope is that these essays will open the way for further dialogue that will continue to radically rethink our understanding of embodied desire. Gathered together here are twelve essays that address these issues from deeply interrelated albeit unique perspectives from within the field. (shrink)

Biopower is a prominent force in mental health, with psychiatry having a strong influential grasp across the areas of definition of mental disorders, diagnosis, care, treatment, and legislation. One area that impacts upon the everyday lives of community mental health service users is treatment, largely dominated by medication. This paper will explore biopower in relation to the practices and management of mental health service users’ medication regimens. Michel Foucault’s insistence in his later work that power is the product of bodily (...) forces will be drawn upon in highlighting the importance of undertaking analysis of medication regimens. Taking examples from a project focused on service user experience, the concept of ‘somatic enactment’ is suggested as a means through which to open up biopower to the localised concerns of service users with regard to the issue of managing one’s body on a day to day basis, as affected by medication. In doing so, the author seeks to move towards a notion of biopower that does not only work on a ‘top down’ manner, and in which processes of embodied subjectification can be illuminated, without recourse to a straightforward power-resistance framework.

Research on patients with damage to ventromedial frontal cortices suggests a key role for emotions in practical decision making. This field of investigation is often associated with Antonio Damasio’s Somatic Marker Hypothesis—a putative account of the mechanism through which autonomic tags guide decision making in typical individuals. Here we discuss two questionable assumptions—or ‘myths’—surrounding the direction and interpretation of this research. First, it is often assumed that there is a single somatic marker hypothesis. As others have noted, however, (...) Damasio’s ‘hypothesis’ admits of multiple interpretations (Dunn et al. [2006]; Colombetti [2008]). Our analysis builds upon this point by characterizing decision making as a multi-stage process and identifying the various potential roles for somatic markers. The second myth is that the available evidence suggests a role for somatic markers in the core stages of decision making, that is, during the generation, deliberation, or evaluation of candidate options. On the contrary, we suggest that somatic markers most likely have a peripheral role, in the recognition of decision points, or in the motivation of action. This conclusion is based on an examination of the past twenty-five years of research conducted by Damasio and colleagues, focusing in particular on some early experiments that have been largely neglected by the critical literature. 1 Introduction2 What is the Somatic Marker Model?3 Multiple Somatic Marker Hypotheses3.1 Are somatic markers necessary for practical decision making?3.2 Speed, accuracy, or both?3.3 At which of the five stages of decision making are somatic markers engaged?4 Anecdotal Evidence Suggests a Peripheral Role for Somatic Markers4.1 Chronic indecisiveness4.2 Extreme impulsiveness4.3 Enhanced decision making in the lab4.4 Lack of motivation. 5 Early Experiments Suggest that VMF Damage Leaves Core Processes Intact5.1 The evocative images study5.2 Five problem solving tasks6 Recent Experiments Fail to Discriminate among Alternate Versions of SMH7 Conclusion.

In a recent article Sachs suggests that the concept of somatic intentionality is the key to understanding how the conceptual order is externally constrained by something outside itself which is nonetheless fully intentional in nature. Sachs claims that his proposal fares better than Sellars’ view on the issue of how our experience can so much as be about objective reality. In this paper, I shall argue that this is not the case because Sellars’ view is in crucial respects misdescribed. (...) Sachs suggests that Sellars’ view is problematic because 1) conceptual intentionality cannot objectively constrain the conceptual order due to its essential discursive form, and 2) a non-intentional consciousness cannot provide an objective worldly constraint on conceptual intentionality because it is not world-directed. However neither of these points succeeds in capturing Sellars’ actual position. Further I will suggest the deepest problem which phenomenological views of a Merleau-Pontyan stripe face in the..

Mystical religious experiences typically purport to engage with the transcendent and often claim to involve encounters with spiritual entities or a detachment from the material world. Daoism diverges from this paradigm. This paper examines Daoist mystical experiences of bodily transformations and explores their epistemological implications. Specifically, we defend the justificatory power of Daoist somatic experiences against the disanalogy objection. The disanalogy objection posits that mystical experiences, in contrast to sense perceptions, are not socially verifiable and thereby lack prima facie (...) epistemic value. We argue that some Daoist mystical bodily states, being essentially spatiotemporal, are exempt from this challenge. This leads to a broader understanding of mysticism and offers a partial resolution to the disanalogy objection. (shrink)

This work begins with a brief review – from the _physical education_ movement that began in ancient Greece and is deeply rooted in 19th century Europe, to the _somatics_ movement alive today. The review captures primary historical and conceptual references, relevant to the therapeutic-embodied exploratory work. Then, G. Stanghellini’s mental health care model [ 2 ] is reviewed. This model is considered within reflexive self-awareness and spoken dialogue: the main vehicles in relation with alterity and its consequences in the realm (...) of psychotherapeutic encounter and intervention. This will highlight the individual’s bodily movement and inter-corporeal ‘proto-dialogue’ as a prior realm of therapeutic intervention. Next, a brief consideration of E. Strauss work [ 31 ] is presented. This paper’s hypothesis is that bodily qualitative dynamics highlighted by phenomenology are essential for an effective mental health therapeutic intervention. A ‘seed’ of a framework is proposed in this paper; this seed assesses some phenomenological assets of a positive conception of mental health, for which self-awareness education is key to develop skills such as _kinaesthetic intelligence_ and _attunement_ and to educate healthy persons who can promote edifying social relations and environments.

This paper explores some ways how perceptual-cognitive accounts of anorexia can benefit from philosophy. The first section focuses on the three dimensions of anorexia most open to a contribution from philosophy: the dimensions of language, perception and cognition. In the second section, I offer a brief overview of what philosophy has to say regarding these dimensions, especially as they relate to two crucial issues: introspection and meaning. I draw from current philosophy of language, especially from the arguments against using internal (...) perception as a model for the way we express our own bodily states. I draw also from current philosophy of interpretation, especially from debates concerning the criteria for handling dialogical misunderstanding. I use these insights to expose some dangers in assuming and working with oversimplified accounts of introspection and meaning. I then suggest refined and updated accounts and examine their applicability and usefulness in the diagnosis and treatment of anorexia. (shrink)

Several recent criticisms of the somatic marker hypothesis (SMH) identify multiple ambiguities in the way it has been formulated by its chief proponents. Here we provide evidence that this hypothesis has also been interpreted in various different ways by the scientific community. Our diagnosis of this problem is that SMH lacks an adequate computational-level account of practical decision making. Such an account is necessary for drawing meaningful links between neurological- and psychological-level data. The paper concludes by providing a simple, (...) five-step model of practical decision making. Recasting SMH in terms of this model generates more precise and empirically tractable computational-level hypotheses about the various ways that somatic markers might influence practical decisions.

This research note challenges the idea that Random Somatic Mutations are entirely random, highlighting their non-equiprobable nature and their influence on evolution, involution, or indeterminacy.

Examining movement learning though Piercean semiotics, this article affirms the basic embodied notion that to utilize one’s body constitutes a form of thought. Through a case study that focuses on theorization of skilled movement in a Japanese martial art that has been transported into North America, I examine processes involved in somatic learning, including both ontological as well as epistemological aspects. I suggest that embodied skills are passed on through story telling, rather than through more conventional models of “passing (...) down information.” Learning somatic skills, or learning more generally, can thereby be conceptualized as a process of attuning judgment, in contrast to acquiring a set of internalized representations about the world.

The prelude to successful human somatic gene therapy, i.e. the efficient transfer and expression of a variety of human genes into target cells, has already been accomplished in several systems. Safe methods have been devised to do this using non‐viral and viral vectors. Potentially therapeutic genes have been transferred into many accessible cell types, including hematopoietic cells, hepatocytes and cancer cells, in several different approaches to ex vivo gene therapy. Successful in vivo gene therapy requires improvements in tissuetargeting and (...) new vector design, which are already being sought. Gene‐transfer protocols have been approved for human use in inherited diseases, cancer and acquired disorders. Althouth the results of these trials to date have been somewhat disappointing, human somatic cell gene therapy promises to be an effective addition to the arsenal of approaches to the therapy of many human diseases in the 21st century if not sooner.

Dorion Cairns correctly interprets the preconstituted stratum of Edmund Husserl’s Fifth Cartesian Meditation to be the primordial ego and not the social world, as was thought by Alfred Schutz, who considered Husserl to be insufficiently attentive to the social world’s hold upon us. Following Cairns’s interpretation, which involves recovering and reconstructing strata that may never exist independently, one better understands how the transfer of sense animate organism involves automatic association, or somatic apprehension. This sense-transfer extends to any animate organism, (...) not just humans, and draws on extensive unreflected-upon similarities despite the distinctive fact that the other’s body is never given to oneself as is one’s own. Following Cairns’s interpretation, one can also understand the second epoché as an imaginative, reconstructive abstraction rather than as an example of failed ascesis. Consequently, Husserl appears as less intellectualized in his approach to empathy than often thought to be and more confident in the phenomenologist’s capacity to imagine and attend selectively to experience.

Clonal disease is often regarded as almost synonymous with cancer. However, it is becoming increasingly clear that our bodies harbor numerous mutant clones that are not tumors, and mostly give rise to no disease at all. Here we discuss three somatic mutations arising within the hematopoietic system: BCR‐ABL, characteristic of chronic myeloid leukemia; mutations of the PIG‐A gene, characteristic of paroxysmal nocturnal hemoglobinuria; the V617F mutation in the JAK2 gene, characteristic of myeloproliferative diseases. The population frequencies of these three (...) blood disorders fit well with a hierarchical model of hematopoiesis. The fate of any mutant clone will depend on the target cell and on the fitness advantage, if any, that the mutation confers on the cell. In general, we can expect that only a mutation in a hematopoietic stem cell will give long‐term disease; the same mutation taking place in a cell located more downstream may produce just a ripple in the hematopoietic ocean.

Based on a presentation at The Undivided Mind conference at Plymouth University, this article sketches out speculative applications of somatics, the first person, phenomenological study of sensation, perception and movement. I first introduce the subject of somatics through an experiential exercise for the reader before summarizing theoretical aspects of somatic study. Drawing from the literature in embodied cognition and from personal recollections of embodied experiences, I propose how somatic approaches could potentially be used in working with immigrant communities, (...) living in outer space, and empathizing with non-human animals.

The gain of a selective advantage in cancer as well as the establishment of complex traits during evolution require multiple genetic alterations, but how these mutations accumulate over time is currently unclear. There is increasing evidence that a mutator phenotype perpetuates the development of many human cancers. While in some cases the increased mutation rate is the result of a genetic disruption of DNA repair and replication or environmental exposures, other evidence suggests that endogenous DNA damage induced by AID/APOBEC cytidine (...) deaminases can result in transient localized hypermutation generating simultaneous, closely spaced (i.e. “clustered”) multiple mutations. Here, we discuss mechanisms that lead to mutation cluster formation, the biological consequences of their formation in cancer and evidence suggesting that APOBEC mutagenesis can also occur genome‐wide. This raises the possibility that dysregulation of these enzymes may enable rapid malignant transformation by increasing mutation rates without the loss of fitness associated with permanent mutators.

Patients with damage to the ventromedial prefrontal cortex (VMPFC) are often described as having impaired ability for planning and decision making despite retaining intact capacities for explicit reasoning. The somatic marker hypothesis is that the VMPFC associates implicitly represented affective information with explicit representations of actions or outcomes. Consequently, when the VMPFC is damaged explicit reasoning is no longer scaffolded by affective information, leading to characteristic deficits. These deficits are exemplified in performance on the Iowa Gambling Task (IGT) in (...) which subjects with VMPFC perform significantly worse than neurotypicals in a task which requires them learn from rewarding and punishing experience to make decisions. The somatic marker theory adopts a canonical theory of emotion, in which emotions function as part of a valencing system, to explain the role of affective processes. The first part of the paper argues against this canonical account. The second part provides a different account of the role of the role of the VMPFC in decision-making which does not depend on the canonical account of emotion. Together the first and second parts of the paper provide the basis for a different interpretation of results on the Iowa Gambling Task (IGT). In fact the IGT may be probing a deficit in what has been called mental time travel: the ability to access and use information from previous experience and imaginatively rehearse future experiences as part of the process of deliberation.
