Mind Control Over a Bull

 José Manuel Rodríguez Delgado, was a physiologist and scientific showman who explored the varied responses of the brain to electrical stimulation.

Here, we see him turn an attacking bull by using a remote control to electronically stimulate a bull's brain so it is forced to stop and turn to one side. Natural behavioral inhibition then follows on (i.e., the brain will tend to follow the body), and the bull relaxes.
