"Unidentified white female between the age of 8 and 10 years old. The subject underwent 6 months of treatment using heavy doses of LSD, electroshock and sensory deprivation. Experiments under codename MKULTRA about early 60s. Subjects memory was erased and her brain is that of a newborn baby."
The CIA-funded MKULTRA mind control program at McGill ran from 1953-64. The infamous Dr. Cameron who directed it was fired in 1964, and died mountain climbing in 1967.
Reportedly the now-famous photo of the little girl strapped down to a table under a sign saying STRAIN ALL URINE, first surfaced on a Japanese blog in 2008. I first saw it at Aangirfan blog, where it has been used repeatedly as an illustration of classified experiments done on children in the MKULTRA project.
The girl in the "Strain All Urine" photo appears to be eight to ten years old.
