Nerve cells are recovering from physical education

Nerve cells are recovering from physical educationNerve cells are recovering from physical education Physical activity has a positive effect on intellectual ability. A group of American scientists from the University of California at Irvine managed to establish the biological mechanisms underlying the effect of training. It turned out that exercise increases the activity of substances that directly stimulates the growth and development of nerve cells. In a study of rats that were allowed to run in the wheel, compared with normal animals. Scientists expect to detect changes only in those areas of the brain that are directly associated with the function of movement. However, the results surprised them. It was found that the activity of stimulatory molecules was observed in those areas that are responsible for memory and intelligence. It was found increased activity of the synthesis of brain-derived neurotrophic factor (BDNF), which, as has been proved earlier, stimulates nerve growth, protects cells from stroke and improve learning processes. This happened mainly in the hippocampus v the structure of the brain responsible for understanding. These changes were manifested after a few days of training. There were also marked changes in such areas as the cerebellum, the lumbar segments of the spinal cord, cortex. Recorded change and other growth factors such as nerve growth factor and fibroblast growth factor-2, but these changes were not as pronounced and there was not so long. This gives reason to believe it BDNF primary point of application of physical activity. Source:Рњednovosti and Madlena.Ru.
