Scary stuff... so when I will see a headline saying "Debugging humans"?

Smiling nervously, the young woman walks forward in a straight line. Suddenly, she veers to the right. She stumbles and stops, attempting to regain her balance, and continues to walk forward. And then she veers off to the left.

No, she's not intoxicated. The young lady's vestibular system, which controls her sense of movement and balance, has been thrown off-kilter by two weak electrical currents delivered just behind her ears. (Click here to see video of a remotely controlled woman.)

This sort of electrical stimulation is known as galvanic vestibular stimulation, or GVS. When a weak DC current is delivered to the mastoid behind your ear, your body responds by shifting your balance toward the anode. The stronger the current, the more powerful its pull. If it is strong enough, it not only throws you off balance but alters the course of your movement.
