BDNF and the Brain

When you exercise, a powerful compound in your brain called BDNF (brain derived neurotrophic factor) is released. BDNF acts to protect and rejuvenate brain cells. The science proves that exercise can dramatically affect the brain. It has been known for years now that BDNF is released when someone exercises "vigorously." However, a new study with elderly individuals proved that 40 minutes of walking 3 times per week for a year stimulates BDNF release and helps the hippocampus region of the brain grow! The hippocampus of the brain is responsible for memory. Get fit and get smart!
