Cortical activation patterns herald successful dream recall after NREM and REM sleep

摘要: Dreaming pertains to both REM and NREM sleep. However, frequency regional specific differences in EEG activity remains controversial. We investigated sleep power density associated with without dream recall 17 young subjects during a 40-h multiple nap protocol under constant routine conditions. was lower for the delta range, particularly frontal derivations, spindle range centro-parietal derivations. low alpha high beta occipital Our data indicate that frequency- topography changes underlie between no after awakening. This dual NREM-REM modulation holds strong implications mechanistic understanding of this complex ongoing cognitive process.
