Phasic activity during non REM sleep

- Intrusion of REM phasic activity into NREM sleep was observed in a RBD patient.
- This case suggests that phasic motor activity may be actively blocked in NREM sleep.
- Jerky and complex behaviors occurred without cortical desynchronization on scalp EEG.
- This phenotype may represent an intermedium stage between RBD and status dissociatus.
