PET, AI show women's brains age differently than men's
By Wayne Forrest
Are women's brains really that much different from men's? In a word, yes. A machine-learning algorithm applied to data from multiparametric PET brain scans showed that women's brains are more "youthful" than those of men of the same age, according to a study published February 4 in the Proceedings of the National Academy of Sciences.
