...cardiovascular fitness so important to cognitive health? Researchers used to think it was all about making sure that plenty of oxygen-rich blood made it to the brain. Now they are starting to suspect there may be more to it. In laboratory animals, at least, exercise also seems to stimulate the body's production of certain molecules called growth factors, which help nerves stay healthy and keep functioning. "We don't understand a lot about why this happens," says Arthur Kramer, a researcher at the University of Illinois who uses brain scans to study the effects of exercise...
...healthy cardiovascular system may even, to some extent, compensate for tiny defects in the brain. Doctors have long known that suffering one or more strokes, which interrupt the flow of blood to the brain, increases the likelihood of dementia. They assumed that Alzheimer's disease was a completely unrelated problem. In fact, a long-running study of a group of nuns who agreed to donate their brains when they died has found that isn't necessarily the case. About a third of the nuns whose brains at autopsy showed clear signs of the plaques and tangles associated with Alzheimer...
That doesn't mean those women wouldn't eventually have developed dementia had they lived long enough. But the study suggested to a lot of physicians that good vascular health may make it easier for a brain with incipient Alzheimer's to work around the plaques and tangles in its midst...
...Virtually all of them. Many people believe creativity comes in a sudden moment of insight and that this "magical" burst of an idea is a different mental process from our everyday thinking. But extensive research has shown that when you're creative, your brain is using the same mental building blocks you use every day?like when you figure out a way around a traffic...
...refer to the three Bs?for the bathtub, the bed and the bus?places where ideas have famously and suddenly emerged. When we take time off from working on a problem, we change what we're doing and our context, and that can activate different areas of our brain. If the answer wasn't in the part of the brain we were using, it might be in another. If we're lucky, in the next context we may hear or see something that relates?distantly?to the problem that we had temporarily put aside...
