Elite athletes succeed by turning off parts of their brain

In high-stakes moments, the human brain often performs best by doing less. Functional MRI scans of expert marksmen and elite athletes show that as the pressure mounts, their prefrontal cortex—the area responsible for complex planning and self-criticism—actually grows quiet. This state, known as transient hypofrontality, allows the brain to bypass conscious hesitation and hand total control to the motor cortex. By temporarily silencing the inner critic, the athlete prevents the 'paralysis by analysis' that causes amateurs to fumble.
