obsessive–compulsive disorder by David W. Evans, Marc D. Lewis, and Emily Iobst, I came across mention of a sex difference so striking I had to post:
[H]man studies show gender differences in callosal axons projecting from the OFC -orbitofrontal cortex]: men attain maximal callosal size in this region at age 20, well ahead of women who do not attain it until 40-50 years (Cowell, Allen, Zalantino, & Denenberg, 1992).We're talking about a 20-year gender gap in development?
Twenty or 30?
And how is it nobody's ever heard about it?
It's not like the orbitofrontal cortex is an insignificant part of the brain, or anything.
