    <br/>

      
        Physiological effects have been observed in a human subject in response to stimulation of 
        the skin with weak electromagnetic fields that are pulsed with certain frequencies near 
        1/2 Hz or 2.4 Hz, such as to excite a sensory resonance. Many computer monitors and TV 
        tubes, when displaying pulsed images, emit pulsed electromagnetic fields of sufficient 
        amplitudes to cause such excitation. It is therefore possible to manipulate the nervous 
        system of a subject by pulsing images displayed on a nearby computer monitor or TV set. 
        For the latter, the image pulsing may be imbedded in the program material, or it may be 
        overlaid by modulating a video stream, either as an RF signal or as a video signal. The 
        image displayed on a computer monitor may be pulsed effectively by a simple computer 
        program. For certain monitors, pulsed electromagnetic fields capable of exciting sensory 
        resonances in nearby subjects may be generated even as the displayed images are pulsed 
        with subliminal intensity.
