28 10129-1 EEG BIOFEEDBACK METHOD AND SYSTEM FOR TRAINING VOLUNTARY CONTROL OF HUMAN EEG ACTIVITY ABSTRACT A biofeedback method and system for use to train a person to develop useful degrees of voluntary control of personal electroencephalogram (EEG) activity. A plurality of EEG potentials from a plurality of locations on the head are individually amplified and filtered in accordance with strict criteria intended for processing in accordance within time constraints limited by natural neurological reactivity. Each resultant signal is processed to provide objective data on brain energies as a function of frequency. Data are presented in real time to the trainee in the form of preselected auditory tones and/or vibro-tactile stimuli indicating with high fidelity the details of EEG activity at a multiplicity of cortical sites. Features of auditory feedback promote learning as well as identification and elimination of spurious artifact states. At periodic intervals, the auditory feedback is supplemented by sensory presentation of digital scores summarizing performance in a metric proportional to brain energy output in the feedback parameters. The scores may be presented as illuminated numerical displays, aurally or both. The system is preferably in an environment designed to control the arousal level of the trainee and the degree of distractibility so as to maximize the learning of voluntary self-control. 1012914N.WP5
