title: Hypersensitivity in the proximal region of the frog retina after weak light adaptation.
abstract: Recordings of b-wave and ganglion cell activities were made in order to investigate whether hypersensitivity could be observed in the proximal region of the frog retina or not. Increase in the amplitude of the b-wave and shortening of the response latency of ganglion cells were observed after the termination of adequate adapting light illumination, suggesting the existence of hypersensitivity in proximal elements of the retina.
