Galvanic Vestibular Stimulation, is basically electric messages that are sent to a nerve in the ear that maintains balance. A person or persons can manipulate this technology for either military purposes or for commercial purposes. The technology is being applied in ATSUGI, Japan and the Mayo Clinic in the U.S, as well as a number of other research institutions around the world. It is being investigated for a variety of applications: biomedical, pilot training and entertainment. It is possible there are more diabolical applications.

The phenomenon is painless but dramatic. Your feet start to move before you know it. I could even remote-control myself by taking the switch into my own hands.
Not much is known why GVS makes people veer when electricity hits their ear but hopefully, more information will be released to the public.
