What are the stages of sleep, the % time spent in each stage, and the EEG waveform associated with each stage?
Awake eyes open = Beta
Awake eyes closed = Alpha
Stage 1, light sleep, (5%) = Theta
Stage 2, deeper sleep, (45%) = Sleep spindles and K complexes
Stage 3-4, deepest, non-REM sleep, (25%) = Delta
REM, (25%) = Beta
