The waveform frequency above 13 kHz are called beta waves. These waves are present in all age groups. They have a smaller amplitude but are symmetrical. The waves are influenced by certain drugs which can augment or reduce them. Drugs like barbiturates or benzodiazepine s augment their occurrence. Other waves present on the EEG include the alpha waves, the delta waves, the theta waves and the gamma waves.

Each wave is caused due to a particular function or reason and has its own specificities. This allows neurologists to interpret these waves to diagnose certain diseases. A normal human has characteristic waves and patterns. Comparing the abnormal patterns with the normal ones allows doctors to diagnose diseases.

Beta

Beta waves are observed in all age groups. They tend to be small in amplitude and usually are symmetric and more evident anteriorly. Drugs, such as barbiturates and benzodiazepines, augment beta waves.
