WebJan 21, 2024 · National Center for Biotechnology Information WebAug 3, 2024 · There are many types of brain waves that an EEG records. The basic brain waves are alpha, beta, theta, and delta waves. There are other more complex waves. Each type of brain wave has a normal frequency, height, shape, and location. A person’s age can also determine whether a certain brain wave is normal or not.
WebNational Center for Biotechnology Information WebHuman EEG largely comprises signal power in a range of frequencies from 1–30 Hz; there is some evidence that higher frequencies may also carry important neurophysiological information, however in most EEG studies — and certainly in ERP studies — the vast majority of research questions concerns EEG signals in the 1–30 Hz frequency range.
