Intracerebral micro-injections of bulbocapnine were made to locate the brain sites of action for the production of catelepsy in rats. The catalepsy was induced after bilateral injection of bulbocapnine into striatal areas. The thalamus and the areas in mesencephalon are less sensitive to bulbocapnine for the production of catalepsy. The results support the suggestion that the bulbocapnine-induced catalepsy arose from the blockade of dopaminergic receptors in corpus striatum.
