Normann, Richard A.; Muller, Jay F.; Kolb, Helga | Synaptic inputs to physiologically defined turtle retinal ganglion cells | Two physiologically distinct, HRP-marked turtle retinal ganglion cells were examined for their morphology, GABAergic, glycinergic, and bipolar cell synaptic inputs, using electron-microscopic autoradiography and postembedding immunocytochemistry. One cell was a color-opponent, transient ON/OFF gangl... | Turtles; Neural Pathways; Synapes; Retinal Ganglion Cells | 1991 |

Normann, Richard A. | Control of retinal sensitivity. I. Light and dark adaptation of vertebrate rods and cones | Rods and cones in Necturus respond with graded hyperpolarization to test flashes spanning about 3.5 log units of intensity. Steady background levels hyperpolarize the rods, and the rod responses become progressively smaller as background level is increased. In cones, higher background levels reduce... | Retina;Light and Dark Adaptation; Recepters; Bipolars; Ganglion Cells | 1974 |
