ABSTRACT
Aggression is a complex, multifaceted behavior often caused by numerous factors and expressed in innumerable ways. Like all complex behaviors, aggression ultimately has its roots in the brain. Although this might sound obvious, discovering the specific neural circuits and neurophysiological processes responsible for engendering aggressive responses has proven anything but simple. The purpose of this chapter is to provide a brief overview of discoveries in both human cognitive neuroscience and animal behavioral neuroscience that have begun to shed light-literally in some cases-on the heretofore mysterious neural processes and connections responsible for producing aggressive behavioral responses.
