FIGURE 15-16 Sex Differences in Brain Volume Women’s brain volume in prefrontal and medial paralimbic regions (orange) is significantly higher than men’s. Men have larger relative volumes in the medial and orbitofrontal cortex and the angular gyrus (green). Orange areas correspond to regions that have high levels of estrogen receptors during development, green to regions high in androgen receptors during development.
