Physical exercises raise working capacity of the brain and stimulate formation of new neurones in brain’s parts in which age changes are connected with age decrease in memory. Such conclusions have been recently represented by the American scientists after they have compared the results of experiments with mice and data of researches with volunteers’ participation.
During the experiments with mice employees of the Colombian University estimated the intensity of a blood-groove in a brain of rodents by means of a magnetic-resonant tomography, and they have also studied cellular structure of the certain departments of a brain of animals.
The results of the experiments have shown that the appreciable increase in a blood-groove observed in mice’s hippocampus, exposed to the raised physical activities.
At the second investigation phase the scientists have involved 11 volunteers into the experiments. The volunteers were offered to pass a 3-month’s course of trainings at the sports club. In view of not having an opportunity of to lead the analysis of fabrics of a brain of participants, the researchers leaned on results of magnetic-resonant tomography.
The data of the experiments, carried out before and after a rate of trainings, have shown substantial growth of a blood-groove in a gear crinkle of the hippocampus - a part of the brain in which functions of memory are concentrated. The gradual decrease in memory, which occurred at the majority of people after 30 years, is accepted to be connected with age reduction of number of nervous cells in a gear crinkle. As the researchers mark, the increase in volume of a blood-groove was in direct ratio to achievements in sport of participants of experiment.
