"Studies using MRI scans and other brain imaging technology have shown that people who regularly did yoga had a thicker cerebral cortex (the area of the brain responsible for information processing) and hippocampus (the area of the brain involved in learning and memory compared with nonpractioners. These areas of the brain typically shrink as you age, but the older practitioners showed less shrinkage than those who did no yoga. This suggests yoga may counter-act age-related declines in memory and other cognitive skills.
"Research also shows that yoga and meditation may improve executive functions such as reasoning, decision making, memory, learning, reaction time, and accuracy on tests of mental accuity." - Harvard Healthbeat, August 21, 2021
