Sleep and memory a post-training REM sleep period to examine changes in P waves affecting reprocessing of recently acquired stimuli. It was found that not only were the P waves increased during post-training sleep but also the density of the waves. These findings may imply that P waves during REM sleep may help to activate critical forebrain and cortical structures dealing with memory consolidation. In a Hennevin et al. study, 1989, the mesencephalic reticular formation (MRF) was given light electrical stimulation, during REM sleep, which is known to have an advantageous effect for learning when applied after training. The rats in the experiment
