title: Ionic basis of hyperpolarizing receptor potential in scallop eye: increase in permeability to potassium ions.
abstract: Photoreceptors of the distal retina of the scallop respond to light with a large hyperpolarizing receptor potential which is caused by a selective increase in permeability to potassium ions.
