I remember seeing on Fox News in the Morning (you all can yell at me later) about a group in England that used that same priciple C4 posted about the remote control hunger on the mouse. Except this group used the electrodes to bypass singals from your brain to your vocal box and ears to allow artificial telepathy between the two subjects. I wish for the life of me I could remember that but this is something that is close enough, even more so for government work.
