28 Rizzolatti G. Sinigaglia C. Anderson F. Mirrors in the Brain: How Our Minds Share Actions and Emotions. Oxford University Press, We have identified mirror neurons for aggression. These cells reside in the nucleus of Cajal, a hypothalamic region referred to as an “attack center” for the past several decades. We demonstrate that this center represents a more abstract percept of aggression, one that evokes an aggressive state in self and reflects such a state in others.
