Photic Drive Response by Brain Wave Feedback

Abstract

We have developed a new system of brain wave feedback to alleviate mental stress. The system picks up alpha waves of a subject using a bandpass filter, smooths the brain wave envelope and invigorates the alpha waves by stimulating the subject with a light whose intensity is modulated by the amplitude of the processed alpha waves. The system can also lowers the frequency of the alpha waves as well as reinforcing them. Favorable results were observed in the experiments.
