1. An improved method of controlling the nervous system of a living organism comprising the steps of: (a) detecting at least one bioelectrical signal from one or more topological locations in said organism's nervous system; (b) passing said at least one bioelectrical signal through at least one electronic means responsive to the presence of at least one characteristic of interest in the waveform of each detected bioelectric signal, each of said responsive means being adapted to provide a first output signal relating to the amount of said characteristic present; (c) producing a visual display responsive to said first one or more output signals, said visual display presenting an image depicting kinesthetic physical movement; and (d) causing said organism to concentrate mentally so as to change the image depicting kinesthetic physical movement on said visual display, said change of depicted image indicating desired and undesired conditions; whereby said organism is trained to alter the waveform pattern of said one or more bioelectrical signals, thereby achieving a desired condition of said nervous system.
