MRI shows that exercise helps memory
Columbia University researchers have proven that exercise improves memory. According to a recent online edition of the Proceedings of the National Academy of Sciences, exercise targets a region of the brain within the hippocampus, known as the dentate gyrus, which underlies normal age-related memory decline. Using an MRI imaging technique, researchers were able to observe neurogenesis, the growth of neurons, within the dentate gyrus region following exercise.
