Cardiovascular fitness is thought to offset declines in cognitive
performance, but little is known about the cortical mechanisms
that underlie these changes in humans. Research using animal
models shows that aerobic training increases cortical capillary
supplies, the number of synaptic connections, and the develop-
ment of new neurons. The end result is a brain that is more
