Researchers from German Universities in Regensburg and Jen determined that when a person is involved in some sort of studies, a mass of his brain's gray substance tends to increase.
Scientists observed brain functions of several adults in the course of their intensive juggling courses. One of the observers Christian Gazer tells, “We did not only observe the actual brain growth after the juggling courses but also the process of degradation to the initial brain mass of those who have not been attending courses for three months.”
Until now, scientists were inclined to believe that a human brain does not increase its mass, unless a person is sick or aging.
Brain growth has been fixed by means of Magnetic Resonance Imaging (MRI). With the help of this device scientists acquired sharp images of gray and white substance of their subjects. “After conducting some calculations on our computer, we saw that a part of gray substance has increased after studies,” claims Gazer. Scientists are yet to establish precise reasons and mechanisms affecting brain growth.
