WebJul 8, 2024 · Alpha brain waves are the main brain wave pattern that develops when a person becomes drowsy and transitions from wakefulness to sleep. They continue during the early phase of sleep until they are replaced by slower theta waves. Alpha waves are also present when a person is awake and relaxing, such as with the eyes closed or during meditation . WebMethods: EEG activity was recorded from 28 university students during both eyes-closed and eyes-open resting conditions, Fourier transformed to provide estimates for absolute power in the delta, theta, alpha and beta bands, and analysed in 9 regions across the scalp.
