Usually‚ serotonin has a calming effect‚ which inhibits aggression. When serotonin levels are low‚ this inhibitory effect is removed and people are less able to control their aggressive behaviour.

Discuss genetic explanations for aggression. Early research concentrated on chromosomal abnormalities but no specific genotype has been associated with aggression.
