What physiological change occurs in the space between neurons during deep sleep to facilitate the removal of metabolic waste?

Answer

The brain’s interstitial space expands significantly

During deep sleep, the interstitial space, which is the area between neurons, expands substantially. This physical expansion allows for the efficient removal of metabolic waste products that build up during the waking hours.
