1. A method of retraining brainwave patterns using direct electrical stimulation feedback, comprising the steps of: securing two or more electrodes to a subject's scalp and/or ears; acquiring EEG (electroencephalography) signal(s) on at least one channel (each channel consisting of an active (+) lead, a reference (−) lead and utilizing a common lead connected somewhere on said subject's body); amplifying the EEG signal or signals via differential amplifier 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, wherein said digital-domain representation is created by using an analog-to-digital converter; creating a signal or signals representing at least one time-domain “distortion” (i.e., either faster or slower) by either performing a Fast Fourier Transform (FFT) or by re-sampling said digital domain representation or representations; differentiating said time distorted signal or signals; and introducing said differentiated signal or signals back onto pairs of input leads via coupling means, wherein said differentiated signal or signals are thus input directly to the brain and nervous system.
