• Hypersexuality is an uncommon consequence of brain injury. We report two cases of markedly increased sexual activity following septal damage sustained in the course of placement of ventriculoperitoneal shunts. These two cases, observations in animal experiments, and descriptions of altered behavior in humans with localized brain dysfunction indicate that a circuit involving the septal nuclei has an important role in the mediation of sexual behavior.
