how does exercise affect learning

The investigators also examined brain slices from the two groups of mice in order to measure a nerve-signaling process known as long-term potentiation, or LTP.

(1999, November 10). But the specifics of that process have remained hazy. It is likely .Howard Hughes Medical Institute. The message of these studies would seem to be that exercise timing and intensity interact to affect memory formation, said Maren Schmidt-Kassow, a professor at the Institute of Medical Psychology at Goethe University in Frankfurt, Germany, who led the study of gentle bicycling and memory. compared with their scores taken soon after they’d been sitting quietly and studying. The researchers also found that exercise was more beneficial for female rats than males, similar to how it differentially affects male and female children with ADHD. He added that these data also confirm that the structural and physiological changes that occurred in the dentate gyrus correlate with a learning behavior associated with this region of the brain. Their test scores were actually worse on the memory test conducted immediately after they’d exercised while reading Aerobic exercise like walking, jogging, or gardening may help your brain’s hippocampus -- the part that’s linked to memory and learning -- grow. He added that these data also confirm that the structural and physiological changes that occurred in the dentate gyrus correlate with a learning behavior associated with this region of the brain. Light-intensity exercise will elicit low but noticeable levels of physiological arousal, she said, which, in turn, presumably help

The effect of exercise on cardiovascular fitness and blood glucose levels is a counterweight to the effect diet has had in inducing impaired glucose tolerance and cardiovascular problems.

Exercise Improves Learning And Memory Date: November 10, 1999 Source: Howard Hughes Medical Institute Summary: Chalk up another benefit for regular exercise. Over the past decade, in study after study in animals and people, exercise has been shown to improve the ability to learn and remember. Moving forward, they investigated a mechanism through which exercise seems to improve learning and memory.

If the exercise is more vigorous, however, it may overstimulate the body and brain, she said, monopolizing more of the brain’s attentional resources and leaving fewer for the creation of robust memories. These new studies don’t explain how, for instance, at a molecular level, exercise affects the creation of individual memories. you have an exam” or other activity that involves memorizing and recalling information “in a few hours, you would probably be better off sitting quietly and studying,” he says. "These observations support the idea that exercise enhances the formation and survival of new nerve cells as well as the connections between nerve cells, which in turn improves long-term memory," Sejnowski explained.

"Exercise Improves Learning And Memory." "We can't ask a mouse if it remembered where the platform was located, so we measure long-term memory by having them swim to the platform," said Sejnowski.After six days of training each group of mice for the swimming task, the researchers began the study. Mice in the exercise group logged an average daily distance of 4.87 kilometers, or 2.92 miles.Both groups were trained to locate a submerged camouflaged platform in a maze that was lying just below the surface in cloudy water.

And, as was the case with neurogenesis, increased LTP occurred only in the dentate gyrus.

The path chosen and time taken reflect long-term memory, or how well the mice recall the platform's location. ScienceDaily.

Mice dislike swimming and instinctively seek the platform as a refuge from the stressful activity. To reach that conclusion, scientists conducting the larger and more ambitious of the new studies, But they heard the words under quite different circumstances. (2009).
