Pulsating blood vessels wash your brain while you sleep
Published in Brain/Neurology.
The word “brainwashing” usually triggers negative associations. But our brain health for sure depends on it. Scientists at the University of Oslo have recently made new and important discoveries about how and why this happens when we are sleeping.
The blood vessels in the brain constrict and dilate in certain patterns while we sleep and this is likely one of the key mechanisms driving the clearance the harmful waste substances from our brain.
“Our discoveries can help us find new ways to treat or even prevent Alzheimer’s disease and other neurodegenerative diseases. These findings can also help to create strategies to deliver drugs to the brain more efficiently,” explains associate professor Rune Enger at the Letten Centre at the University of Oslo.
