Code-named MKULTRA, the project was the brainchild of CIA Director Allen Dulles, who was intrigued by reports of mind-control techniques allegedly conducted by Soviet, Chinese and North Korean agents on US prisoners of war during the Korean War. The CIA wanted to use similar techniques on its own POWs and perhaps use LSD or other mind-bending substances on foreign leaders, including Cuba's Fidel Castro, a few years after the project got underway in 1953. In addition to LSD, Cameron also experimented with various paralytic drugs such as curare, as well as insulin shock therapy and ECT at thirty to forty times the normal power. This was part of what he called depatterning. His "psychic driving" experiments consisted of putting subjects into drug-induced comas for weeks at a time while playing tape loops of noise or simple repetitive statements. Cameron defined "depatterning" as breaking up existing patterns of behavior, both the normal and the schizophrenic, by means of particularly intensive electroshocks, to wipe the human mind totally clean.
