WebApr 5, 2024 · EEG can be divided into 2 two main components, rhythmic activity, and transients. The rhythmic activity of the brain can be divided into bands according to frequency. The frequency ranges from less than 4 Hz to 32 Hz. The frequency bands can be divided as follows- Delta Theta Alpha Beta Gamma Mu WebThe frequency of frontal midline theta varies from 5-7.5 Hz, with an average of 6Hz. This rhythm is associated with working memory, episodic encoding and retrieval. It also appears during hypnosis and deep meditation. …
