Healthy children are smarter

Physically, healthy children have higher IQs than their peers, and new studies have confirmed this. Scientists have found that aerobics are suitable for children aged 9 to 10 in areas where their brains have more "white matter". White matter consists of nerve fibers, or neuronal axons, connecting different brain regions. Previous studies have found that the "grey matter" of the child's constitution has a greater brain capacity and neuronal cell body.
Dr. Laura Chadak Hyman, Ph.D., chief researcher at the University of Illinois, said: "This study extends our previous work and points out that the white matter structure may be an additional mechanism that is more suitable for children than their low-contract age. Cognitive tasks and in the classroom." The team used brain scan technology called diffusion tensor imaging to examine the five white matter fiber bundles of 24 volunteer children.
The working principle of the system is the diffusion analysis of water molecules into the tissue. For white matter, less water diffusion means that the tissue is more fiber and compact, whatever desirable qualities. Significant body-related differences occur mainly in several key white matter areas, including the corpus callosum connecting the left and right hemispheres. The other two upper longitudinal bundles, a pair of two four large valves connected to the cortex in the brain and superior radiographic corona connect the cerebral cortex to the brainstem.
"All these areas have been found to play a role in attention and memory," Chadakheimman said. Although the team did not test the child's psychological performance, previous studies showed a connection between aerobic exercise and improved thinking skills.
