摘要:: Voltage-gated ionic current and the response to quinine were studied on the four types of morphologically identified taste cells of the bullfrog fungiform papilla by whole-cell patch clamp recording with a Lucifer yellow-filled pipette. Dye-coupled type Ia cells (mucous cells) did not show voltage-activated currents. Type Ib cells (wing cells) characterized by the fin-like processes, type II cells (rod cells) having a thick straight dendrite running to the surface and type III cells with a thin dendrite had voltage-gated sodium (INa) and potassium currents (IK) and generated action potentials. The amplitude of INa was significantly larger in type Ib and II cells than in type III cells. Type Ib and II cells responded to quinine but Type III cells did not.
