It is thought that the 40 Hz gamma wave is important for the binding of our senses in regards to perception and are involved in learning new material. Brain Waves: Frequencies To Understand. Before I get into specifics, it is important to realize that when I refer to a certain brain wave, I am implying that a particular brain wave is âdominant.â Throughout the day in your waking state, your EEG will display all 5 types of brain waves at the same time.
