A group of military veterans are suing to get the CIA to come clean about allegedly implanting remote control devices in their brains.
It's well known that the CIA began testing substances like LSD on soldiers beginning in the 1950s but less is known about allegations that the agency implanted electrodes in subjects.
A 2009 lawsuit (.pdf) claimed that the CIA intended to design and test septal electrodes that would enable them to control human behavior. The lawsuit said that because the government never disclosed the risks, the subjects were not able to give informed consent.
Bruce Price, one plaintiff in the lawsuit, believes that MRI scans confirm that the CIA placed a device in his brain in 1966.
