Abstract: An improved method and means for bio-feedback training of living organisms, utilizing one or more electro-neuro signals to produce tactile sensations on the skin of the organism. One or more electrical characteristics of such electro-neuro signals are responsive to a particular condition of the organism which is detectable in a physiological signal produced by the organism at a selected location on its body. The tactile sensation experienced by the organism is, thus, a function of the detected condition, and the organism can learn to alter such condition by concentrating on increasing or inhibiting the tactile sensation.
