5-Hydroxytryptamine (serotonin; 5-HT)2 receptor agonists such as (+/-)-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) injected systemically or directly into frontal cortex, elicit stereotyped head movements that are mediated by 5-HT2A receptors. Chronic administration of 5-HT2A receptor antagonists can produce either a down-regulation, e.g., d-2-bromolysergic acid
