WebSleep stages are characterized by spectral content of EEG: for instance, stage N1 refers to the transition of the brain from alpha waves (common in the awake state) to theta waves, whereas stage N3 (deep or slow-wave sleep) is characterized by the presence of delta waves. The normal order of sleep stages is N1 → N2 → N3 → N2 → REM. WebBeta brain waves occur between 14 - 30 Hz but during intense mental activity can reach 50 Hz i.e., Beta waves characterize the conscious waking state at 14 cycles per second and up. Beta waves occur in individuals who are attentive and alert to external stimuli or exert specific mental effort. WebApr 7, 2024 · One way that EEG ‘brainwaves’ convey information is in their rate of repetition. Some oscillations, measured on the scalp, occur at more than 30 cycles per second (and up to 100 cycles per second!) These cycles, also called frequencies, are measured as Hz, or hertz, after the scientist who proved the existence of electromagnetic waves. gap grand central
