Yoga Boosts Brain Gray Matter
The scientists found that the brains of the yoga meditation practitioners contained significantly greater gray matter by volume in key brain regions, including the frontal, temporal and occipital cortices, plus the cerebellum and the hippocampus, compared to the non-yoga subjects.
The yoga meditation practitioners also had more gray area in the prefrontal cortex regions that are involved in decision-making, reward/consequence, control and coordination.
