Abstract
A method of retraining brainwave patterns using direct electrical stimulation feedback comprises: securing two or more electrodes to a subject's scalp and/or ears; acquiring EEG signal(s) on at least one channel; amplifying the EEG signal or signals via differential amplifier means; digitizing said EEG signal or signals via Analog-to-Digital converter means; selecting at least one of said channels from which to derive feedback; creating at least one digital-domain representation of said selected EEG signal or signals; creating a signal or signals representing at least one time-domain “distortion” of said digital domain representation or representations by time distortion means; differentiating said time distorted signal or signals; and introducing said differentiated signal or signals back onto the pairs of input leads via coupling means, wherein said differentiated signal or signals are thus input directly to the brain and nervous system, bypassing the normal systems of perception.
