Neural map of a typical woman‘s brain     Neural map of a typical man‘s brain Sex differences are of high scientific and societal interest because of their prominence in behavior of humans and nonhuman species. This work is highly significant because it studies a very large population of 949 youths (8–22 y, 428 males and 521 females) using the diffusion-based structural connectome of the brain, identifying novel sex differences. The results establish that male brains are optimized for intrahemispheric and female brains for interhemispheric communication. The developmental trajectories of males and females separate at a young age, demonstrating wide differences during adolescence and adulthood. The observations suggest … Continue reading Madhura Ingalhalikara, Alex Smitha, Drew Parkera, Theodore D. Satterthwaiteb, Mark A. Elliottc, Kosha Ruparelb, Hakon Hakonarsond, Raquel E. Gurb, Ruben C.
