The development of sex differences in infantile autism. Kail, R. Many of such sex differences described in the human brain arise during development by an interaction of sex hormones and the developing neurons, although direct genetic effects are probably also involved [ ].

The PFC is thought to be involved in decision making. Sex differences need to be considered in studying brain structure and function and may raise the possibility of sex-specific treatments for neurological diseases.

Hemispheric superiority in reaction time to faces: a sex difference.
