Wired reported on it in 2011. Seems like a real thing. http://www.wired.co.uk/magazine/archive/2011/04/start/mind-c...
I'd have thought that if this were a real thing, it'd be way better known - the psychiatric industry would be committing minor flesh wound to get their hands on it, for example. A drug that can suppress free will while leaving the patient conscious and responsive could revolutionise therapy.
Though I agree the whole thing sounds made up.
