Webb1 apr. 2024 · Gamma waves, which measure between 25 and 100 Hz, are the fastest wavelength brain waves that are linked to activities such as learning, problem-solving, and information processing. What They Do When the brain produces alpha waves, it is because it is in a state that is relaxed and restful. Slow brain waves, or slow wave activity (SWA), refer to the EEG patterns seen during non-rapid eye movement (non-REM) stages of sleep. SWA is thought to play a critical role in memory consolidation and overall brain function.

WebbSleep 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.
