Exercise helps sustain mental activity as we age, may prevent dementia-like illnesses
..."Aerobically trained older adults showed increased neural
activities in certain parts of the brain that involved attention and reduced activity in other parts of the brain that are sensitive to behavioral conflict," said Kramer. Animal studies also provide support for the aging benefits of physical activi...

New mechanism explains glucose effect on wakefulness
One of the body's basic survival mechanisms is the neural
