Translations:Orientation Selective Ganglion Cell/3/en

OSGCs have oval-shaped concentric receptive fields that favor either the horizontal or vertical orientation. The stimuli that were used in the study by Levick in 1967 to demonstrate the orientation selectivity of these cells were narrow strips of light oriented in different directions on the receptive fields. The cells responded to these stationary strips of light when presented at the preferred orientation of the ganglion cell. Some of these cells responded only when the strip of light was presented in the horizontal direction, and the others responded more strongly when presented in the vertical direction. It was also determined that these cells respond to strips of light when the intensity contrast between the strip of light and the background is 1/5.
