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.

Preparing some slides on my favourite topic of the moment - #HippocampalReplay - for some colleagues, starting from lecture slides I made about 8 years ago...
and I keep crossing stuff or adding "BUT see xx" or "actually not" or "Now controversial!" to about half of the results that I was taking from granted 8 years ago 👀

Is there any such thing as a scientific fact?!

#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.

Gedanken allein lassen das Gehirn nicht „wachsen“ oder „schrumpfen“. Doch chronischer Stress kann messbare Auswirkungen auf bestimmte Hirnregionen haben.

🧠 New preprint by Chericoni et al: #NeuralPopulation activity in the #hippocampus encodes spatial information for different agents (self, prey, gaze) in distinct but related low-dimensional subspaces. The study shows that these representations can be linearly transformed between each other, suggesting a shared geometric code supporting flexible spatial #cognition and multi-agent navigation.
