The Brain Circuit Behind Male Libido Has Been Identified in Mice : ScienceAlert

The sex drives of male mice seem to arise from a single, newly identified brain circuit, a new study reveals.

This circuit governs a male mouse’s sex drive and its resulting behavior and reward experience, suggesting it plays a vital role in compelling them to reproduce.

And while that’s interesting, the US researchers are curious about more than just motivations for mouse sex. This brain circuitry is probably ancient, they note, given its apparent importance in persuading male mice to mate.

A brain circuit this fundamental is unlikely to change much during the course of evolution, the team…
