Abstract

A description is given of an L.E.D. light panel display powered by an Electroencephalograph machine with some of its applications. The EEG machine powers a panel array of lights displaying electrical brain waves picked up by corresponding head probes. This new method discloses brain wave signal phase relationships, frequency, intensity, and areas of activity to medical technical personnel. The lights are arrayed exactly as the sensing probes are arranged on the head of the person being examined. The panel array itself is composed of light emitting diodes (LEDs) powered by the brain wave signals from the output amplifiers of the EEG machine. The LED lights require little power and are capable of frequencies well beyond those encountered in the human brain. These frequencies of from 1/2 Hertz to 60 Hertz and their associated amplitudes are very perceptable to the human eye when displayed on the panel as flickering lights. The use of the SIDI in conjunction with the permanent electroencephalogram provides the medical technical analyst with immediate interrelated multichannel information in a readily comprehensable form.
