What we ‘see’ in the brain depends on which tool we use to ‘look’ – but each one comes with trade-offs.

There was considerable beta band amplitude increase, including significant increase in beta2 amplitude across all cortical brain areas Most of the treatment-related EEG changes were rapid ...

The researchers analyzed the signals collected from each subject, which included delta, theta, alpha, beta, and gamma EEG band powers.

The average overall activity is a mix of many different frequencies, with the five main ones called delta, theta, alpha, beta and gamma waves. If the EEG were just random up-and-down drift – “the ...

Find out what you need to know about gamma brain waves, and discover what they are and how they may affect health.

"Strikingly, we also revealed that melodic expectations selectively enhanced EEG reconstruction accuracy in the beta band for musicians, and in the alpha band (8–12 Hz) for non-musicians ...

Brain state work can be couched in terms such as alpha, delta and so forth. However, this is actually referring to brain waves which specifically come from measuring brain activity using EEG.
