Brain Biology

While few people would seriously argue that one sex is more intelligent, researchers have found that the brains of men and women do differ physically.

  • Brain Size: Men have larger brains than women by about 8-10%.
  • Corpus Callosum Size: Many researchers believe that a woman's brain has a larger corpus callosum, which is the pathway connecting the right and left cerebral hemispheres. Some researchers claim this larger size enables women to process information more quickly than men between the two sides of the brain.
  • Cortical Thickness and Density: Women’s brains possess more folding. Some researchers speculate this is why women’s brains are smaller overall.
