Abstract

This chapter examines the influence of neurotransmitters and drugs on aggressive behaviour. It examines the possible role of four specific types of neurotransmitters on aggression. These are acetylcholine, norephinephrine, dopamine, and serotonin. The results of experimental work and clinical studies reveal that dopamine and serotonin inhibit agression while norepinephrine and acetylcholine increase aggression when administered to the temporal lobe, hypothalamus, or other neural areas. Drugs found to be associated with increased aggression include phencyclidine, inhalants, and anxiolytics.
