Delta Waves 2 (5 Minutes) | L 60 Hz - R 64 Hz
A delta wave is a high amplitude brain wave with a frequency of oscillation between 0.5 and 4 hertz. Delta waves, like other brain waves, are recorded with an electroencephalogram (EEG) and are usually associated with the deep stage 3 of NREM sleep, also known as slow-wave sleep (SWS), and aid in characterizing the depth of sleep.
