title: Orientation bias of cat retinal ganglion cells: a reassessment.
abstract: For cat retinal ganglion cells whose receptive field centres were distributed in specified sections of the left visual field, the deviations of the major axis from the radial, horizontal, and circumferential directions were determined. The percentage of cells with deviations within +/- 20 degrees from the radial, horizontal, and circumferential directions were, respectively, 33%, 68%, 16%. In addition, comparison between values of deviation from the horizontal direction for cells located at eccentricities of 10 degrees and 20 degrees from the area centralis showed a statistically significant trend; the bias for the horizontal increased with eccentricity.
