In rats morphine, like chlopromazine, produced catalepsy and raised striatal homovanillic
acid levels. Analysis of interactions between each of these cataleptogenic agents and
naloxone, 1-DOPA and apomorphine strongly suggests that morphine influences striatal
dopamine (DA) metabolism and produces catalepsy by a mechanism different from that of
chlorpromazine.
