By the time you reach your twenties, your brain is functioning at its peak. After this, little by little, the number of neural connections declines. Your working memory may become a bit less reliable, and you may not focus as well or react as quickly. Fortunately, the more actively you use your brain, the more likely it is to stay sharp as long as you live.
Give your brain a workout this fall in one of our many courses for adults. Sign up now for Sackler Brain Bench - Neuroscience of Sports, a five-week course that begins on September 16.
