Men and women are actually from the same planet, but scientists now have the first strong evidence that the emotional wiring of the sexes is fundamentally different.
An almond-shaped cluster of neurons that processes experiences such as fear and aggression hooks up to contrasting brain functions in men and women at rest, the new research shows.
For men, the cluster "talks with" brain regions that help them respond to sensors for what's going on outside the body, such as the visual cortex and an area that coordinates motor actions.
For women, the cluster communicates with brain regions that help them respond to sensors inside the body, such as the insular cortex and hypothalamus. These areas tune into and regulate women's hormones, heart rate, blood pressure, digestion and respiration.
"Throughout evolution, women have had to deal with a number of internal stressors, such as childbirth, that men haven't had to experience," said study co-author Larry Cahill of the University of California Irvine. "What is fascinating about this is the brain seems to have evolved to be in tune with those different stressors."

An almond-shaped cluster of neurons. So, is this why people are nuts? :rofl:
