Total sleep deprivation (TSD) has been consistently found to impair encoding of information during ensuing wakefulness, probably through suppressing NonREM (non-rapid eye movement) sleep. ...
TSD significantly decreased both the rate of correctly recognized pictures and of recalled frames associated with the pictures. ...
This effect has been attributed to the loss of non-rapid eye movement sleep (NonREM) rather than REM sleep during TSD before learning, and specifically to functions of slow waves (0.5-4 Hz) and spindles ...

The aim of this study was to investigate this hypothesis using selective REM-sleep deprivation. We used a recognition memory task in which participants were shown negative and neutral pictures. ...
Sleep enhances memory consolidation and it has been hypothesized that rapid eye movement (REM) sleep in particular facilitates the consolidation of emotional memory. ...
The technique of REM-sleep deprivation is therefore an interesting approach to also analyze sleep-related emotional memory processes. ...
