Q
REM sleep
A
= paradoxical sleep
- beta waves (as in bein awake)
- EEG desynchronization
- PGO waves before waking up
- LGN and primary visual cortex activity
- less frontal lobe
- skeletal muscle paralysis
- genital activity
6

- delta waves
- deepest
- fragmented dreams
- strong stimulus suppression
