raging bull

[Michael Sylvester]

Jose Delgado implanted electrodes in the brain of a bull and using
a remote control switch was able to stop the bull from attacking
the matador. I read somewhere that this inhibitory aggression was not
due to the action of the remote switch but there might have been other
factors involved.
Will someone elucidate me on this?
