Overall scanning of the brain showed that the juggling increase the size of certain parts of the brain. However, the termination of such an exercise leads to a reduction in those same areas. Researchers from the University of Regensburg (Germany) are involved in their experiment, 24 people who did not have any experience before this juggling.
After the first half of the brain research subjects were asked to learn how to juggle three balls and three months to perform these exercises daily for at least 60 seconds. After that, all 24 people were again scanned the brain. The brain of representatives of the control group did not change, and in the minds of those who have learned to juggle, increased two areas related to the processing of visual information.
After scanning the first group stopped juggling, and the experiment continued for another three months. During this time (as shown in the third scan) decreased amount of gray matter.
