I have to add to this relevant study by Bernardi et al. that we found that REM shares some homeostatic mechanisms in response to sleep deprivation, as indicated mainly by the similar direction and topography of changes in low-frequency activity (Marzano et al., 2010).
Interestingly, we also found a dissociation within the range of slow waves, with <2 Hw SWA not involved in this homeostatic response. At that time, we interpreted the dissociation in terms of state-specific homeostatic mechanisms for NREM sleep during recovery sleep [limited to the very low frequencies
(<2 Hz) and to sigma activity], and shared homeostatic mechanisms between REM and NREM sleep, involving >2 Hz , theta and alpha activity.Reference:
