The activity of genes in men's brains begins to change sooner than it does in women's brains, a new study shows.
Men and women’s brains age differently, a new study demonstrates.
Researchers led by Carl Cotman and Nicole Berchtold at the University of California, Irvine, find that the activity of genes in men’s brains begins to change earlier than it does in women’s brains. The types of genes that change with age also differ between the sexes.
The study, which appears online September 22 in the Proceedings of the National Academy of Sciences, also found that in both genders, each part of the brain examined had its own pattern of aging.
“This is a very interesting study in what is, curiously, an under-studied area, normal aging,” says Etienne Sibille, a neuroscientist at the University of Pittsburgh, who was not involved in the study. “You have a combination of expected and surprises in each finding.” For instance, the fact that men and women’s brains age differently could
