Sleeping is by far one of the most imperative biological needs for majority of organisms. It is comprised of 4 stages: NREM 1, NREM 2, NREM 3, and REM. In NREM 1, it is considered as light sleep. This stage transition from awake state (Alpha Wave, about 8 to 13 Hz) to onset of sleep (Theta Wave, about 4 to 7 Hz). In NREM 2, it consists about 45 to 55% of total sleep in adult and is characterized by sleep spindles (12 to 14 Hz) and k-complexes. This stage …show more content…
