The emetic action of L-dopa and its effect on the swallowing reflex in the cat

In adults cats anesthetized with urethane it was shown that facilitation of reflexly-induced swallowing by dopaminomimetics is caused by a central action independent of the emetic of such drugs. It is suggested that this modulatory influence is mediated by dopamine receptors associated with the amygdala and ventral basal striatum.
