Abstract:In mammals, males execute a stereotypical and organized sequence of sexual behaviours, such as mounting, intromission, and ejaculation, to successfully complete copulation. However, the neural mechanisms that govern the sequential transitions of male copulatory behaviours remain unclear. Here, we report that dopamine (DA) and acetylcholine (ACh) dynamics in the ventral shell of the nucleus accumbens (vsNAc) closely align with serial transitions of sexual behaviours in male mice. In particular, the vsNAc exhibi… Show more
