Never Mind Your Abs -- Tone Your Brain - Forbes

"You may just be more likely to find your car in the parking lot if you’ve briskly walked there. Why? Because your brain needs physical exercise as much as your body does. You can get a date without abs, but just try getting that attractive stranger to go out with you if you forget your prospect’s name.Neuroscientists have found that exercise increases blood flow and the release of beneficial chemicals including dopamine, norepinephrine, and serotonin, plus a substance known as BDNF (brain-derived neurotrophic factor), which essentially fertilizes new neurons, or brain cells."

Can You Build a Better Brain?

The explosion in neuroscience is slowly revealing the mechanisms of cognition. “We have accumulated enough knowledge about the mechanisms and molecular underpinnings of cognitionat the synaptic and circuit levels to say something about which processes contribute,” says James Bibb of the University of Texas Southwestern Medical Center...Greater cognitive capacity comes from having more neurons or synapses, higher levels of neurogenesis (the creation of new neurons, especially in the memory-forming hippocampus), and increased production of compounds such as BDNF (brain-derived neurotrophic factor), which stimulates the production of neurons and synapses, says neuroscientist Yaakov Stern of Columbia University. Both neurogenesis and synapse formation boost learning, memory, reasoning, and creativity. And in people who excel at particular tasks, Stern’s neuro-imaging studies show, brain circuits tend to be more efficient (using less energy even as cognitive demand increases), higher capacity, and more flexible.
