The difference between an old brain and a young brain isn't so much the number of neurons but the presence and function of supporting cells called glia. In a new article, researchers who examined postmortem brain samples from 480 individuals ranging in age from 16 to 106 found that the state of someone's glia is so consistent through the years that it can be used to predict someone's age.
