A brief list of 34 government patents are provided on inventions achieving some form of mind control. Some of the patents on this list were issued under the CIA's MK-Ultra project. This secret program performed grisly electroshock and torture methods on hundreds of unsuspecting CIA victims from the 1950's to 1970's. One victim of Dr Ewen Cameron's grisly treatment was deliberately overdosed with insulin and placed into a coma for 21 days, where they severely electroshocked him many times – erasing his conscious memory. Dr Cameron even bragged that he could turn an ordinary person into a vicious serial killer, using these methods. There is evidence that this CIA program continues today, under a different name, in spite of Congressional orders to shut it down. The CIA continues to fund research and pursue political targets using mind control. This is a new technology that targets people while sleeping and employs specific frequencies (about 3900 MHz).
