Sleep cleans the brain: Researchers develop fast, non-invasive way to measure the process

Sleep helps the brain to cleanse itself—and now this process can be measured in humans entirely noninvasively. Researchers at the University of Oulu have developed a method that allows the increased movement of brain fluids during sleep to be tracked quickly and safely, without the need for injected contrast agents.

How Slow Waves During Sleep Take Over to Clear Metabolic Trash

Researchers have developed a non-invasive MRI method to measure the brain’s self-cleansing process. The study reveals that during sleep, vascular pulsations take control of brain dynamics to accelerate waste removal.
