Run, run, which will improve the memory



From Italian journal

Who's going to the gym usually smiles when he muscled boys recite the famous phrase of Juvenal "mens sana in corpore sano." Yet a study conducted by the Department of Experimental Psychology at the University of Cambridge in collaboration with the National Institute on Aging in Baltimore, confirmed what is suggested by the Roman poet - shown obviously by young beefy above. The research, published in the pages of the important scientific journal 'Proceedings of the National Academy of Sciences', Journal of the United States National Academy of Sciences, purpose was to understand how physical activity improves brain function. The results show that the sports that raise the heart rate, and aerobic such as running, increase the number of new brain cells with the resulting increase in memory in subjects studied.

The research was carried out on two groups of mice in the laboratory during a period of 105 days, but the team at Cambridge think that the results of the study may be valid for humans. During the observation period, a first group of mice could practice without limitations on a wheel, running on average for more than 20 miles a day. The second, however, did not exercise. At the end of the period of 105 days, both groups were subjected to a test of memory. Was shown a box where their food came out when touched, after which the box was removed and confused with others. The mice "runners" were able to effectively preserve the memory, as opposed to more passive ones. Timothy Bussey of Cambridge University says that, of course, "even the mice had idle capacity to remember, but those sports were much more adept at distinguishing between similar memories, which made their finest memory." As demonstrated by the Anglo-Saxon studies, this particular aspect of memory is improved by physical activity. "The human equivalent would be having to remember where you parked your car not only today but in two different days of the previous week. It becomes difficult to distinguish memories when events are similar, "said Bussey. At the end of the experiment, rats that ran on the wheel had, then, a number of new brain cells more than double compared to inactive rats. Tests on mice have shown, therefore, that intensive and regular aerobic exercise can increase the capacity by encouraging the construction of new brain cells in the 'convolution teeth', a region of the hippocampus that are known for a long time ties with memory and learning as well as its weakness that starts as early as 30 years of age.
