Brains, white and grey

For what it’s worth, the AP runs this story on the on going scientific research that seems to support some difference between the brains of men and women; they use their brains differently in some situations, but there is no difference in IQ’s.

In recent years, scientists have found that male and female brains are wired differently from one another, due to the role of testosterone and other male hormones during gestation. Brains growing under the influence of male hormones are slightly larger and have denser concentrations of neurons in some regions.

Male brains also contain a greater proportion of gray matter, the part of the brain responsible for computation, while women have relatively more white matter, which specializes in making connections between brain cells.

Brain-imaging studies suggest that both sexes exploit these differences to their benefit. UCLA researchers have done brain scans of men and women who scored in the top 1 percent on the math section of the SAT. As they worked on math problems, the men relied heavily on the grey matter in the brain’s parietal and cerebral cortices. Women showed greater activity in areas dominated by the well-connected white matter.
