Neuroscientists find that different parts of the brain work best at different ages

"'If you go into the data on gene expression or brain structure at different ages, you see these lifespan patterns that we don't know what to make of. The brain seems to continue to change in dynamic ways through early adulthood and middle age,' Germine says. 'The question is: What does it mean? How does it map onto the way you function in the world, or the way you think, or the way you change as you age?'"
