Eight elderly Canadians who were victims of CIA-funded brainwashing experiments in the 1950s reached a tentative out-of-court settlement Tuesday in their multimillion-dollar damage suit against the U.S. spy agency.

The Canadian plaintiffs, who say they suffered permanent mental and physical damage as a result of the bizarre experiments performed on them at a Montreal psychiatric hospital, will divide a $750,000 payment among them, according to their attorney, James Turner.

The Canadians, all patients of the late Dr. Ewen Cameron at Montreal's Allan Memorial Institute in the late 1950s, were injected with repeated doses of mind-altering LSD, deprived of sleep, subjected to massive electroshock treatments and forced to listen to thousands of repetitions of taped messages taken from the most sensitive moments of their therapy sessions.
