Researchers uncover cleansing system of the brain during sleep
Researchers from the University of Copenhagen have mapped the brain's glymphatic system that cleanses toxic by-products during sleep, revealing implications for sleep drugs like Ambien.
As you lay your head down to sleep tonight and dream all things weird and wonderful, scientists believe your brain engages in a gentle rinse cycle, washing away a day's worth of toxic by-products in preparation for the next day.
