Sleep, Stress, and Your IQ: How Everyday Habits Quietly Shape Your Cognitive Performance

If sleep deprivation is the blunt instrument that batters cognitive performance, chronic stress is the slow poison. The biological mechanism is well understood, and its effects on the brain regions most critical to intelligence are profound.

How does stress impact #navigational performance? This study shows that #cortisol administration impairs path integration, a specific navigational process, and reduces grid-like brain activity patterns in the #entorhinal #cortex @PLOSBiology https://plos.io/3NmX3eG
Cortisol treatment impairs path integration and alters grid-like representations in the male human entorhinal cortex

Stress impacts navigational performance and involves cortisol release, but how cortisol impacts brain functions supporting navigation remains unclear. This study in men shows that cortisol administration impairs path integration, a specific navigational process, and reduces grid-like brain activity patterns in the entorhinal cortex, offering new insights into the effects of stress on navigation.

The #stress #hormone #cortisol severely disrupts the brain's internal navigational system by impairing the function of grid cells in the entorhinal cortex, causing acute spatial disorientation.

How Stress Disrupts the Brain’s Navigational System

People under stress may have a harder time spatially orienting themselves.

#studien zeigen, dass anhaltender Stress mit strukturellen Veränderungen im #hippocampus und im präfrontalen Kortex in Verbindung steht – Bereiche, die für #gedächtnis #Emotionsregulation und Entscheidungsprozesse wichtig sind. #Stresshormone wie #cortisol spielen dabei eine zentrale Rolle.
