Explore the frequency labels used to describe EEG rhythms.

Hz

0.5 Hz ← frequency axis → 100 Hz

Gamma · 30–100 Hz

Fast EEG rhythms studied in sensory processing and other research contexts.

Band boundaries vary across sources. Here a boundary belongs to the next band: 4 Hz is theta, 8 Hz alpha, 13 Hz beta, and 30 Hz gamma. Gamma extends beyond the 100 Hz limit shown here.

These labels describe measured electrical activity, not guaranteed effects of playing a tone or flashing a screen. Sound pulses, binaural beats, and visual flicker are different stimuli. This is an exploration tool, not a treatment.
