Karate black belts' white matter shows how a powerful punch comes from the brain

Karate black belts' white matter shows how a powerful punch comes from the brain: Brain scans have revealed distinctive features in the brain structure of karate experts, which could be linked to their ability to punch powerfully from close range. Researchers found that differences in the structure of white matter -- the connections between brain regions -- were correlated with how black belts and novices performed in a test of punching ability.
