The Angry Brain: Neural Correlates of Anger, Angry
Rumination, and Aggressive Personality
Thomas F. Denson1, William C. Pedersen2*, Jaclyn Ronquillo3*,

Abstract
& Very little is known about the neural circuitry guiding anger,
angry rumination, and aggressive personality. In the present
fMRI experiment, participants were insulted and induced to
ruminate. Activity in the dorsal anterior cingulate cortex was
positively related to self-reported feelings of anger and individual
differences in general aggression. Activity in the medial
prefrontal cortex was related to self-reported rumination
and individual differences in displaced aggression. Increased
activation in the hippocampus, insula, and cingulate cortex
following the provocation predicted subsequent self-reported
rumination. These findings increase our understanding of
the neural processes associated with the risk for aggressive
behavior by specifying neural regions that mediate the
subjective experience of anger and angry rumination as well
as the neural pathways linked to different types of aggressive
behavior. &
INTRODUCTION
Despite the enormous costs of anger and aggression,
very little is known about the neural mechanisms guiding
these phenomena (Davidson, Putnam, & Larson, 2000).
Understanding these neural mechanisms is important
because it provides insight into concrete, biological processes
that predispose individuals for aggression. The
uncovering of these processes has long been a central
concern of neuroscience as well as social, clinical, personality,
and forensic psychology.
For most people, angry feelings dissipate within 10 to
15 min (Tyson, 1998; Fridhandler & Averill, 1982). However,
recent research suggests that dwelling on angerinducing
experiences (i.e., angry rumination) may be
particularly harmful because it increases aggression over
extended periods of time, even toward the innocent
(Bushman, Bonacci, Pedersen, Vasquez, & Miller,...
