Aggression as rewarding as sex, food and drugs

NASHVILLE, Tenn.—New research from Vanderbilt University shows for the first time that the brain processes aggression as a reward - much like sex, food and drugs - offering insights into our propensity to fight and our fascination with violent sports like boxing and football.

The research will be published online the week of Jan. 14 by the journal Psychopharmacology.

“Aggression occurs among virtually all vertebrates and is necessary to get and keep important resources such as mates, territory and food,” Craig Kennedy, professor of special education and pediatrics, said. “We have found that the ‘reward pathway’ in the brain becomes engaged in response to an aggressive event and that dopamine is involved.”
