WebThe homeostatic process, which is derived from the time course of slow-wave activity, is represented by a linear increase during wakefulness, and a linear decline during sleep. In ideal, non-sleep deprived scenarios the interaction between the homeostatic sleep drive and the circadian process is relatively synchronous. WebThe different stages of sleep are marked by changing patterns of the EEG. During stage 1, 2 and 3 of NREM (light sleep), the predominant brain waves are theta waves (4-7 Hz). In Stage 4 (Deep Sleep) delta waves (.5-4 Hz) predominate and vital signs are at their lowest. This is the stage where sleep walking and night terrors occur.
