Numerous studies suggest that frontal-lobe dysfunction may serve as a significant risk for violent or aggressive behaviors. The frontal lobe, which constitutes approximately one-third of the cerebrum, extends from the anterior (forward) tip of the brain to the central sulcus. Its surface consists of several subregions, which have distinctive patterns of connections with other areas of the cerebral cortex, along with structures deep below the surface of the brain. Because of its unique composition, placement, and connectivity, the frontal lobe is thought to play a key role in various complex functions, including those related to aggression, violence, and antisocial behavior. Extensive research in multiple areas of the neurosciences—brain imaging, neurology, neuropsychology, and psychophysiology—continues to produce evidence that more and more clearly defines this role.
