By Tohoku University - Published on 02 August 2026
The dreaming brain surges with energy, yet its neurons may consume it faster than they can replenish it. A new mouse study from Tohoku University has uncovered a surprising energy imbalance during rapid eye movement (REM) sleep. As the brain entered this dream-rich stage, blood volume increased across the cortex, and astrocytes accumulated more metabolic [...]
