Newly released files from behavior modification," or mind control, projects conducted as part of the infamous Project MKUltra reveal the CIA experimented in more than controlling humans with psychotropic drugs, electrical shocks and radio waves-they also created field operational, remote-controlled dogs. The documents were provided under the Freedom of Information Act (FOIA) by John Greenewald, founder of The Black Vault, a site specializing in declassified government records. In one declassified letter (released as file C00021825) a redacted individual writes to a doctor (whose name has also been redacted) with advice about launching a laboratory for experiments in animal mind control. The writer of the letter is already an expert in the field, whose earlier work had culminated with the creation of six remote control dogs, which could be made to run, turn and stop. The letter writer characterizes the work with remote-controlling dogs as a success, describing "a demonstrated procedure for controlling the free-field behaviors of an unrestrained dog." Attached to the letter is the writer's final report from his earlier research, published in 1965, titled "Remote Control Behavior with Rewarding Electrical Stimulation of the Brain," with the principle investigator's name redacted. The prospect of a potential new laboratory seems to fire the letter writer's imagination, who describes potential experimentation on "a range of species," should they want to move past "basic research."
