Dorsolateral Prefrontal Cortex

Alexithymia in High Performers: Why Emotional Blindness Fuels Success — Until It Doesn’t Alexithymia in high performers is the neurobiological pattern in which the anterior insular cortex underactivates while the dorsolateral prefrontal cortex compensates by substituting analytic reasoning for the visceral-emotional signal the brain cannot produce. The substitution works. It produces visible competence across every domain — until the cognitive load it requires exceeds what compensation can carry, and the entire architecture collapses at once. ...

Decision Fatigue Is a Prefrontal Pricing Error: How Your Brain Secretly Inflates the Cost of Thinking Decision fatigue brain science has moved past the willpower-tank model. Recent neuroscience shows the brain inflates the perceived cost of thinking through a pricing error — the right anterior insula amplifies effort signals while the dorsolateral prefrontal cortex fails to recalibrate. The result: you start avoiding decisions at exactly the wrong moment. ...
