"SUPER BRAIN"   Host Carol Castiel and reporter Courtney Bernard speak with Dr. Rudy Tanzi, professor of neurology at Harvard Medical School, about his new book “Super Brain,” which explains how the brain is constantly evolving and improving throughout our lifetime as long as we take care to "use it" rather than let it “use” us. Tanzi gives practical advice regarding how we can all attain a "super brain" through proper diet, intellectual stimulation, physical activity and mindfulness.
