Isochronic Tone Augmented Biofeedback System

摘要

A biofeedback system that utilizes isochronic tone technology to augment EEG feedback by providing to a subject isochronic tones at the frequency of a targeted aspect of a subject's brain waves, such as the brain's naturally occurring peak energy in the particular EEG band or bands subject to the biofeedback. Isochronic tones are regular beats of a single tone that are formed by separate pulses of sound and silence. In addition, feedback can be provided to the subject in the form of pulsed light and pulsed tactile impulses that are delivered in the form of alternating presence and absence of light or tactile pressure.

主权项

1. A method for training a person to develop useful degrees of voluntary control of personal electroencephalographic (EEG) activity, said method comprising the steps of:
(a) securing EEG leads to the person; (b) receiving an EEG signal from the person; (c) transmitting the resultant EEG signal to a filter; (d) filtering the EEG signal; (e) monitoring a predetermined EEG frequency band or subband; (f) determining the EEG frequency value of a preselected aspect of said EEG signal; and (g) generating a isochronic signal in which the isochronic frequency of the signal is set according to the value of said EEG frequency value.
