Quizplus · Accepted Answer

The first EEG stage of a night's sleep is stage 1. This stage is characterized by light sleep and slower brain waves compared to wakefulness. Alpha waves are typically present during wakefulness and relaxation, not during the initial stage of sleep. Stages 3 and 4 are deeper stages of sleep that occur later in the night, while stage 2 is the stage that immediately follows stage 1.
