Exercise protects the Dopamine part of the brain from damage

Judy Cameron at the University of Pittsburgh studied the effect of exercise on the brains of monkeys. In her experiment some monkeys remained sedentary and others exercised for five hours per week. After 3 months the monkeys were given a neurotoxin that kills dopamine cells in the brain. As expected, the sedentary monkeys had considerable brain damage but amazingly the monkeys who had exercised showed almost no brain damage at all. The more intense the exercise, the more protection there was from the brain damage. The results continued to hold up even when the experiment was extended longer. It is not known if exercise protects our brains from damage from other poisons, but these results sure are encouraging.
