Abstract

Four studies have examined the cross-sectional area of the anterior commissure (AC) for variation with sex, with conflicting results. One also reported the AC to be larger in homosexual as opposed to heterosexual men. We examined the cross-sectional area of the AC in postmortem material from 120 individuals, and found no variation in the size of the AC with age, HIV status, sex, or sexual orientation.
