Running might be a smarter pursuit than earlier imagined. Apart from improving cardiovascular fitness and overall physique, it actually might make you brighter, according to scientists reporting in the Proceedings of the National Academy of Sciences. It appears from experiments that running profoundly impacts the hippocampus, the part of the brain that controls learning and memory. Studies conducted on mice showed that those voluntarily engaging in activities like running wheels did, in fact, manage to increase their number of brain cells and performed better at cognitive tests compared to non-exercising mice. Until the late 1990s, neuroscientists held the belief that new brain cells didn't grow after birth. However, that premise stands challenged in the face of mounting evidence suggesting exercise touches off significant physiological and structural changes in the brain conducive to enhanced cognitive functioning. Looks like a perfectly sound reason to get off the couch, slip on your running shoes and jog off to the neighboring park...
