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.
Similarly our heart and our brain have wave patterns. The wave pattern of the heart is measured by ECG (electro cardiograph). The brain waves are measured by EEG (electro encephalograph). Using the brain wave studies, scientists have discovered that our brain waves are of four types. The brain waves also have peaks that are similar to the peaks we see in water waves.
