"Noisy" Neurons in Cognitive Aging

Why do Many Cognitive Functions Decline as We Age?

On September 17, UCSD Cognitive Science Prof. Bradley Voytek will address the question: “Why do many cognitive functions seem to decline as we get older?” Studies show that after peaking in the late teens and early 20s, our ability to remember and attend appears to worsen with age.
