Quizplus · Accepted Answer

Deep, restorative, slow-wave sleep occurs during Non-REM Stage 3, which is characterized by high-amplitude, low-frequency delta waves on the EEG recording. Non-REM Stage 1 and 2 are lighter stages of sleep with less delta wave activity, and REM sleep is characterized by rapid eye movements and low-amplitude, high-frequency waves on the EEG recording. Therefore, the best choice is C, Non-REM Stage 3.
