TL;DR: It is shown that aerobic exercise training increases the size of the anterior hippocampus, leading to improvements in spatial memory, and that increased hippocampal volume is associated with greater serum levels of BDNF, a mediator of neurogenesis in the dentate gyrus.

TL;DR: This study provides the first evidence for exercise-induced functional plasticity in large-scale brain systems in the aging brain, using functional connectivity techniques, and offers new insight into the role of aerobic fitness in attenuating age-related brain dysfunction.

TL;DR: The findings are the first to indicate that aerobic fitness may relate to the structure and function of the preadolescent human brain and the hypothesized specific effect of fitness on the hippocampus.

TL;DR: Results are consistent with animal models of exercise and the brain, but are the first to show in humans that exercise-induced increases in temporal lobe functional connectivity are associated with changes in growth factors and may be augmented by greater baseline VEGF.

TL;DR: It was found that most regions involved in dual-task processing before training showed reductions in activation after training, and many of the decreases in activation were correlated with improved performance on the task.
