When more blood does not mean more neuronal energy during REM sleep
REM sleep is already called "paradoxical sleep. " The body is largely still, yet the brain is highly active.
AI Summary
Research has uncovered a paradoxical aspect of REM sleep, a stage characterized by high brain activity despite the body's relative stillness. During REM sleep, the brain's blood volume increases, which might suggest a corresponding boost in neuronal energy. However, a recent study found that this increased blood flow does not translate to more ATP available within neurons. This discovery challenges the conventional understanding of how the brain functions during REM sleep, a stage closely linked to vivid dreaming.
