Worldwide Campaign to stop the Abuse and Torture of Mind Control/DEWs
This article in New Scientist describes research by scientists in Israel involving nano bots which were injected into cockroaches attached to an electromagnetic coil. The bots contained drugs, and had a gate which when heated released the drug. A man wearing an EEG cap attached to the coils, switched on the coils by either doing a mental calculation or having his brain at rest.
The idea is to apply this to human brains.
