WebbSleep-related slow wave activity (SWA; 0.5–4 Hz) is one brain activity pattern detectable at the human scalp during sleep [ 7 ]. This EEG pattern occurs predominantly in NREM stage 3 (N3) and consists of two independent components, namely Scalp-Slow wave (SW) (< 1 Hz) [ 8] and delta power (1.0–4 Hz) [ 9 ]. WebbA slow brain wave on an EEG is known as a delta wave. Delta waves typically have a frequency of 1 to 4 hertz (cycles per second) and are the largest in amplitude out of the five main types of brain waves. Slow delta …
