My brain freezes under stress — why?

'Brain freeze' under stress matches acute prefrontal cortex inhibition by the amygdala. Executive functions (reasoning, language, planning) are cut in under 250ms when the alarm system takes over.

Warum es passiert — der Mechanismus

The amygdala detects threat 60ms before cortex. It signals locus coeruleus releasing noradrenaline + cortisol → prefrontal inhibition. Consequence: impossible to think, speak coherently, plan. You fall back on habits (good or bad).
