Sleep's Symphony: How Brain Waves, Blood Flow, and Fluid Oscillations Work Together
Do Brain Waves, Blood Flow, and Spinal Fluid Move in Sync During Sleep?
Yes, and this coordination is essential for sleep’s restorative functions. This landmark study revealed that during human sleep, brain electrical activity, blood flow, and cerebrospinal fluid movement oscillate together in a precisely coordinated symphony. These coupled oscillations create optimal conditions for waste clearance, memory consolidation, and brain restoration—showing that sleep isn’t just the absence of wakefulness, but an active, orchestrated process that maintains brain health.
