Abstract
...

One night of sleep deprivation impaired clearance of the tracer substance from most brain regions, including the cerebral cortex, white matter and limbic structures, as demonstrated on the morning of Day 2 after intervention (sleep deprivation/sleep).

Moreover, the impaired cerebral clearance in the sleep deprivation group was not compensated by subsequent sleep from Day 2 to 3. The present results provide in vivo evidence that one night of total sleep deprivation impairs molecular clearance from the human brain, and that humans do not catch up on lost sleep

Interesting, especially for those of use with what can only be classified as severe insomnia. Yours, Lenora.

So one night of impaired sleep screws the brain for life?
Or do they need to look past 3 days?
