To date, most sleep deprivation studies have focused on acute sleep deprivation, suggesting that acute sleep deprivation can cause significant damage to cognitive, emotional, and physical functions and brain mechanisms. [11] Few studies have compared the effects of acute total sleep deprivation and chronic partial sleep restriction. [8]

A meta-analysis of several studies regarding sleep deprivation suggests that the effects of partial sleep deprivation are underestimated.
This study gives evidence that REM sleep is a significant factor in consolidating motor skill procedural memories, therefore sleep deprivation can impair performance on a motor learning task. This memory decrement results specifically from the loss of stage 2, REM sleep. [11]
