THE race to put man on the Moon wasn't enough of a battle for the global super powers during the Cold War. At the time, the Soviet Union and the United States were in an arms race of a bizarre, unconventional kind - that has been exposed in a new report. The Soviets poured at least $1 billion into developing mind-controlling weaponry to compete with similar programs undertaken in the US. While much still remains classified, we can now confirm the Soviets used methods to manipulate test subjects' brains. The paper, by Serge Kernbach, at the Research Centre of Advanced Robotics and Environmental Science in Stuttgart, Germany, details the Soviet Union's extensive experiments, called "psychotronics". The paper is based on Russian technical journals and recently declassified documents outlining practices from 1917 to 2003. See the details on News.com.au.
