MKUltra Subproject 62

Project MKUltra Subproject 62 ran from June 26, 1966, with continuing funding. The surviving paperwork shows financial and administrative records. The project's purpose was to partially finance studies on the effects of physical and chemical agents on the central nervous system of arthropods. The status section notes that certain kinds of radio frequency energy had been found to effect reversible neurological changes in chimpanzees, with follow-up studies underway. The ledger pages document expenses from 1956 through 1960, including deposits, travel costs, equipment purchases like an electroshock unit and camera equipment, stenographic services, animal care expenses (described as 'safe house' repairs and maintenance), and various project-related trips. Total documented expenditures through the period shown amount to approximately $19,785.26 in credits against a balance of $7,390.20 as of mid-1959. Expenses reference multiple project codes including LSD project, RF project, and beagle project designations.
