They really do! A new study reveals that the way that the visual centers of men and women’s brains works is different: Men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors. In fact, most of the people who are colorblind are men.
In the brain there are high concentrations of male sex hormone (androgen) receptors throughout cerebral cortex, especially in the visual cortex, which is responsible for processing images. Androgens are also responsible for controlling the development of neurons in the visual cortex, meaning that males have 25% more of them than females.
