: The most common stage; features sleep spindles and K-complexes . See visual waveform examples on Learning EEG

: Brain activity resembles wakefulness ("activated" EEG), but with muscle paralysis and rapid eye movements. 3. Clinical Applications

Low-voltage, fast-activity EEG, dominated by alpha (relaxed) and beta (active) waves. B. NREM Stage 1 (N1) - Light Sleep
