Relation of pharmacological and behavioral effects of a hallucinogenic amphetamine to distribution in cat brain

The hallucinogen 2,5-dimethoxy,-4-methylamphetamine, also known as STP, accumulates in specfic areas of cat brains. The unchanged compound was detected in the brain for at least 6 hours, whereas its behavioral effects lasted for about 4 hourS. The coincidental pharmacological and behavioral effects of the compound apparently indicate a relation between the anatomical distribution and action.
