EEG Frequency Bands

EEG waveforms are generally classified according to their frequency, amplitude and shape, as well as the location on the scalp at which they are recorded: 

  • 0.5 - 3   Hz: Delta  = Deep Sleep
  •    4 - 7   Hz: Theta = Light Sleep
  •    8 - 13 Hz: Alpha = Awake and Relaxed
  •  14 - 30 Hz: Beta   = Awake and Excited

The next table shows the location and state associated to the most familiar classification used for EEG waveform frequency.

    Hi. Do you mind if I use the information from your chart in the introduction of my thesis? If you don't mind, how can I reference you?
