Neural control of sex differences in affiliative and prosocial behaviors.

Abstract

Social interactions are vital for various taxa and species. Prosocial and affiliative dynamics within a group and between individuals are not only pleasurable and rewarding, but also appear to actively contribute to well-being, cognitive performance, and disease prevention. Moreover, disturbances in acting or being prosocial can represent a major burden for an individual and their affective partners. These disruptions are evident across a spectrum of neuropsychiatric conditions, including depression and autism spectrum disorders. Importantly, interactive patterns of prosocial and affiliative behavior can vary with sex. The fact that genders are differentially affected by neuropsychiatric disorders associated with social impairment underscores the high importance of this research in uncovering the underlying neural correlates and mechanisms. This review focuses on elucidating sex-related differences in prosocial and affiliative behaviors and their potential association with sexually different neural correlates. Specifically, we aim to shed light on the complex interplay between sex, behavior, and neurobiology in affiliative and prosocial interaction patterns.
