As we fall asleep, our brain’s energy use and metabolism slow down, while blood flow becomes more dynamic—especially in sensory areas to keep us alert to the environment. This coordinated shift supports brain waste clearance and overall neural health, revealing sleep’s vital role beyond rest. Fascinating insights from cutting-edge EEG-PET-MRI imaging show how sleep balances brain energy and blood flow to keep us sharp and refreshed. #BrainHealth #SleepScience
