The science of mind control is advancing at a furious rate. In 2011, the NYTimes reported that scientists had engineered neurons to be sensitive to light and then using fiber optic cables and brain implants they were able to quickly turn mice neurons on and off, instantly changing the behavior of the mice (paper here). The setup, which required genetic engineering, brain implants and cables worked incredibly well but a rather expensive method of mind control.
Moreover, the scientists think that the genetic modifications can be done with a simple injection:
If the tools for mind control can be injected then it doesn't seem fanciful to think that they can be ingested. Mind control in a bottle. The fear is outside mind control but the reality will be self mind-control. Humans have been altering their minds for thousands of years but neuronal level adjustment at the flick of a switch is something new.
