Document Summary
Smart jocks: cardiovascular itness is associated with higher intelligence. Exercise increases hippocampal neurogenesis in both young and older animals. Shows the number of new cells ater the intervenion. Exercise helps to proliferate new cells in the hippocampus. Exercise increases growth factors: brain-derived neurotrophic factor (bdnf) 3 groups: control, exercise for 3 days, exercise for 7 days. Even just ater 3 days of exercise, there"s an upregulaion of bdnf, not an accumulaion over ime. When you exercise you get an increase in the expression of bdnf which helps to produce new brain cells in the hippocampus. If they run a further, they had more mrna expression = more neurogenesis. Exercise-induced neurogenesis in the dentate gyrus of the hippocampus. Dendrite gyrus: where the new cells are born, then they migrate up and integrate into the network. Bdnf is helping to create more cells in the dg.
