We are on the brink of a new understanding of the neuroscience of violence. Like detectives slipping a fiber optic camera under a door, neuroscientists insert a fiber optic microcamera into the brain of an experimental animal and watch the neural circuits of rage respond during violent behavior.
We like to believe that we are in control of our actions, but sometimes we are not. A sudden incident can overtake conscious will and launch us into violent action that risks our life and limb in an instant. I know, because it happened to me.
