Selective REM-sleep deprivation does not diminish emotional memory consolidation in young healthy subjects.

Results Manipulation Check When comparing the percentage of REM sleep across the two nights for each experimental group we found a highly significant decrease of REM sleep from 11.9%±1.2 (mean ±SEM; adaptation night) to 1.4%±.4 (experimental night) in the REM deprivation group (p<.001; paired t-test) and a slight increase in the undisturbed sleep group (12.4%±1.2 and 15.7%±1.4; p = .07).
