From "Scientific American Frontiers"

Excerpt from above link

emory, like most brain abilities, seems to suffer fewer ravages of aging in individuals who keep mentally active. Scientists believe this may be due to the continued reinforcement of the brain cell pathways along which thoughts travel. As you think, messages move along the living network of brain cells. When a brain cell is stimulated, it releases chemicals called neurotransmitters. Some neurotransmitters carry messages to neighboring cells. Others maintain the health and longevity of the inter-cellular connections. Still others encourage the growth of new cell connections to produce even more robust pathways. So by using an assortment of thinking pathways, you can sustain and even improve the fitness of your network of brain cells."
