These are my notes on dot point 4: which is what your referring to:
Awake EEG: beta waves: high F, low A
NREM Stage 1 (drowsy)EEG: alpha waves: mid-high F, mid-low AEMG: Reduction in muscle tension (but muscles still active)
Other sign: hypnic jerk
EOG: May be slow, rolling movements
NREM Stage 2 (light sleep)EEG: theta waves = low F, mixed A. Sleep spindles (burst of high F)K complexes (burst of high A).EMG: Medium ActivityEOG: No movement
NREM Stage 3 (sleep)EEG: theta & delta waves = higher A, lower FEMG: Medium or Low AEOG: No movement
NREM Stage 4 (deep sleep)EEG: delta waves = high A, low FEMG: Medium or Low AEOG: No movement
REM (Rapid Eye Movement)EEG: Beta waves: irregular bursts of high F, low AEMG: Low A (temporary paralysis)
EOG: Sharp, intermittent eye movements
Sleep cycles of 90mins through night.
NREM stage 1 to 4, then back, then REM.
More time in NREM at start of night
More time in REM later in night
