Limbic stimulation-induced hypersexuality

Abstract

Postictal sexual drive levels induced by limbic discharges were studied in eight adult male cats. Although sexual drive was exclusively dependent upon the presence or absence of testosterone, the level or degree of drive was dependent on the relative amounts of circulating testosterone and catecholamines in addition to the bioelectric state of the testosterone-binding cells. The limbic discharge was thought to induce postictal hypersexuality by its propagated discharge, suppressing the association neocortex and simultaneously activating the sexual hormone-binding cells of the diencephalon. The dissociation of the neocortex from the diencephalon was considered as a functional postictal diaschisis. These postictal physiologic changes were thought to account for the irrational automatic behavior and memory loss characteristic of patients with psychomotor seizures.
