Flashcards in Sleep Deck (7)
What would you expect to find on an EEG, EOG and EMG in the awake stage?
EEG: Fast activity, high frequency, beta activity
EOG: Some eye movements
EMG: Strong muscle tone
What would you expect to find on an EEG, EOG and EMG in the stages 1&2 of sleep?
Slow wave/NREM sleep
EEG: brain activity slows, theta activity, drowsiness
EOG: No eye movements
EMG: Muscle tone reduces
What would you expect to find on an EEG, EOG and EMG instates 3&4 of sleep?
EEG: brain activity is even slower, delta activity, low frequency
EOG: no real eye movement
EMG: low muscle tone
What would you expect to find on an EEG, EOG and EMG in stage 5 of sleep?
EEG: fast brain activity, similar to beta activity
EOG: wide eye movements
EMG: minimal muscle tone
How long is one typical sleep cycle?
What are the bodily functions that are synchronised to NREM and REM sleep?
NREM: slow HR and respiration decreases
REM: HR and respiration rate increases
