POTENTIALS OF INDIVIDUAL SEMICIRCULAR CANALS IN FROGS AND THE EFFECT OF OTOTOXIC DRUGS

抄録

Using isolated semicircular canals of frogs and a stimulator which induced a current of fluid within the ampulla, the electrical response of each three ampullar receptors were tested. The adaptation time of isolated posterior ampullar receptors was also measured and the action of several ototoxic drugs on the ampullar receptors on the isolated posterior semicircular canal of the frog and the intracellular rest potential from the posterior semicircular canal crista were investigated.
