Disinhibited sexual behaviour has been reported following damage to the frontal lobes, particularly the orbitofrontal region of the limbic system.

Kolarsky and colleagues54 examined the relationships between “sexual deviation”, age of lesion onset and localisation of lesion (temporal vs extratemporal). The authors defined two diagnostic categories: (1) “sexual deviation”, involving a deviation of sexual object (for example, paedophilia). [[Homosexuality]] was included in this category, which would now be considered inappropriate, and (2) “sexual disturbances other than deviations”, including orgasm in response to stimuli unrelated to the subject's sexual preference, hypersexuality and hyposexuality...
