Scientists uncover an energy paradox in the brain during REM sleep

A recent study published in Communications Biology provides evidence that the brain manages its energy resources in surprisingly different ways depending on whether it is in a deep sleep or a dreaming state. By monitoring live brains, scientists observed that during rapid eye movement sleep, the brain receives a surge of blood and energy nutrients, yet the actual energy levels inside neurons drop. This indicates that the sleeping brain might pri…

Brain's Energy Paradox: REM Sleep Shatters Metabolic Rules

The Brain’s Energy Paradox: Why REM Sleep Defies Metabolic Logic The brain during dreams behaves like a reckless gambler—spending its last reserves while its accounts are being replenished. A new study published in Communications Biology reveals that rapid eye movement (REM) sleep is not merely a rest period but an "energy paradox," where the brain’s usual metabolic rules break down. How the Brain Fuels Itself in Wakefulness Neurons are the body…
