Abstract

Depue & Morrone-Strupinsky (D&M-S) present a thorough case for the role of “reward” brain circuits in affiliative bonding. Integration of information in the nucleus accumbens shell (NA), the role of dopamine in this processing, and opioid (primarily via mu receptors) control of these circuits are the primary elements of the model. Although the overall picture is quite compelling, the description leans excessively in the view of dopamine systems as “reward” circuits.
