types of brain waves frequency
In the past gamma waves were not researched to the same extent as the other four brain waves. Today they have gained more popularity and are known to be associated with perception and consciousness. Gamma waves can be between 26 and 70 Hz but most often corresponds to frequencies of 40 Hz or higher.
Specifics of the Individual Brainwaves. 1  Beta Waves. Beta waves have a low amplitude but are the fastest of the four brain waves. 2  Alpha Waves. According to frequency order Alpha brainwaves are next. 3  Theta Waves. Theta waves are even slower than the Alpha waves and have higher amplitude.  Delta Waves.
