More Differences Between Brains of Men and Women
S left and the right sides of the brain. After allowances for men’s larger overall head and brain size, men had roughly 6 percent more IRL tissue than women.“The inferior parietal lobule is far more developed in people than in animals and has evolved relatively recently,” says Pearlson. It allows the brain to process information from senses such as vision and touch, and enables the sort of thinking involved in selective attention and link the right IRL with a working memory of spatial relationships, the ability to sense relationships between body parts and awareness of a person’s own affect or feelings. The left IPL, Pearlson says, is more involved in perception, such as judjing how fast something is moving, estimating time and having the ability to mentally rotate 3-D figures.“To say this means mean are automatically better at some things than women is a simplification,” says Pearlson. “It’s easy to find women who are fantastic at math and physics and men who excel in language skills. Only when we look at very large populations and look for slight but significant trends do we see the generalizations. There are plenty of exceptions, but there’s also a grain of truth, revealed through the brain structure, that we think underlies some of the wa
