EEG (Electroencephalogram) : 뇌파 EMG (Electromyograph) : 근전도
EOG (Electrooculography) : 안구운동 EKG (Electrocardiogram) : 심전도
Sleep stage I
Alpha activity in the EEG drops to less than 50%
Lasting for 1-7 minutes.
Amplitudes are less than 50-75mV
A burst of activity on the EEG, EOG, and EMG
Sleep stage II
Delta is permitted for less than 20%
Amplitude may increase from that seen in stage I
K-complexes appear for the first time
Sleep spindles may appear
Sleep stage III
The EEG shows slower activity for between 20% and 50% of the epoch
Peak-to-peak amplitudes greater than 75mV
Both K-complexes and sleep spindles
No specific criteria exist for EOG and EMG
Sleep stage IV
The EEG shows 4 cps or slower activity, with peak-to-peak amplitudes greater than 75mv for at least 50% of the epoch.
muscle tone decreases gradually from stage II to stage IV
A burst of activity on the EEG, EOG, and EMG
