APA Dictionary of Psychology

a procedure in which electrical signals are sent to the nerves in the ear to control balance and body orientation and movement. GVS is used to treat visual neglect, to compensate for damage to or disorders affecting the inner ear, in pilot and aerospace training, and for virtual reality entertainment, among other applications. The stronger the electrical currents, the stronger the effect on balance. The currents are delivered by external electrodes, but implants are being studied as a possible delivery method.
