Art Kramer is a Professor of Psychology and the Director of the Center for Cognitive Brain Health at Northeastern University. In this podcast he talks about how aerobic exercise can improve several aspects of brain performance including learning and memory, and multitasking. His brain imaging studies in elderly people have shown that exercise can increase the amounts of gray and white matter in some brain regions, and can enhance the functional connectivity of neuron networks. Importantly, exercise improves academic performance in children. On the other hand lack of exercise and overeating adversely affect brain structure and performance.
