Electroencephalogram (EEG) trace of a subject,showing brain activity in the range of 0 - 25 Hz (cycles per second). At the center of the frame is the area corresponding to 13.25 Hz which is being stimulated by a flashing light. This subject,however,is able to amplify the response to the light (large peak). This is the result of training using biofeedback techniques. The amplified response at this frequency may be detected and used to activate a computer - in this case it is used to command a flight simulator to turn right | |
