EEG data are combined with those from concurrent recording of eye movements from the electrooculogram (EOG), and muscle tone from the electromyogram (EMG) to define the states of sleep and wakefulness. (scholarpedia.org)
In contrast to wakefulness, sleep is characterized by higher voltages and slower waves, a pattern called synchronized EEG. (scholarpedia.org)
At sleep onset in humans, the low voltage, high frequency EEG pattern of wakefulness, often with alpha waves when the eyes are closed, gradually changes to Stage 1 sleep as the EEG frequencies slow. (scholarpedia.org)
Stage 1, a brief transitional phase after wakefulness, is followed by Stage 2 sleep when EEG frequencies slow further. (scholarpedia.org)
