Athletes' performances have evolved considerably over the last twenty years. The extraordinary talent of some champions intrigues neuroscientists today. Thanks to technological progress, they now have tools to understand what lies behind the talent of these champions. By observing the brains of exceptional athletes, researchers have identified how the mechanisms of learning and memorizing technical gestures operate at the heart of neurons. They have been able to observe to what extent intensive and daily physical training modifies the cerebral cortex and can also increase cognitive abilities tenfold.
