1. A multiple afferent sensory stimulation device providing audio and visual sensory stimulation to a patient comprising:

  • a playback device adapted to receive a pre-recorded program and to emit audio stimulation signals and a plurality of visual stimulation control signals;

    means operably connected to said playback device to separate the visual stimulation control signals from the audio stimulation control signals, said means including a high pass filter to block the audio stimulation signals while passing the visual stimulation control signals;

    means operably connected to said playback device to provide audio stimulation to at least one of the patient'"'"'s ears;

    a pair of tone decoders operably connected to said means separating the visual stimulation control signals from the audio stimulation signals, one of said tone decoders adapted to emit a signal output upon receipt of a visual stimulation control signal of a first frequency, and a second of said tone decoders adapted to emit a signal output upon receipt of a visual stimulation control signal of a second frequency;

    a logic circuit connected to said pair of tone decoders adapted to receive signal outputs from said first and second tone decoders, said logic circuit adapted to ignore false signals from either said first or second tone decoders; and

    means operably connected to said tone decoders to receive the decoded visual stimulation control signals for displaying visual stimulation to at least one of the patient'"'"'s eyes whereby audio and visual stimulation is provided a patient in accordance with the pre-recorded program to induce sensory reactions into the patient.
