报告简介：Positive prosocial interactions contribute to the development and maintenance of a range of adaptive, cooperative behaviors. Conversely, inability to participate in normal social interactions is a debilitating symptom of several prominent neuropsychiatric disorders.  Although the role of neuromodulators in social behaviors, in particular oxytocin, is an active area of investigation, relatively little is known about the detailed neural mechanisms that influence sociability.  We have pursued the hypothesis that the release of serotonin (5-HT) from dorsal raphe (DR) neurons in the mouse nucleus accumbens (NAc), a key node of classic reward circuitry, is critical for promoting non-aggressive prosocial interactions.  We find that bidirectional modulation of 5-HT release in the NAc robustly modifies sociability in opposing directions, while having minimal effects on control behaviors.
