A clear link between brain speed and intelligence.

The bright spaghetti structures represent the pathways connecting different brain cells. clipped from www.npr.org DTI is a variant of magnetic resonance imaging (MRI) that can measure the structural integrity of the brain's white matter, which is made up of cells that carry nerve impulses from one part of the brain to another. The greater the structural integrity, the faster nerve impulses travel Thompson says DTI scans of the 92 participants in the study revealed a clear link between brain speed and intelligence. When you say someone is quick-thinking, it's genuinely true The impulses are going faster and they are just more efficient at processing information, and then making a decision based on it clipped from commons.wikimedia.org
