We found an anisotropy of perceptual "filling-in" at the physiological blind spot. The stimulus was a pair of lines presented for 200ms with one line on each side of the blind spot. The length of the lines extended gradually whenever an observer pushed a key on a computer keyboard. The observer's task was to report whether the line appeared 'complete' or 'gapped' when compared to a reference line presented simultaneously to the temporal retina. The independent variable was the orientation of the line. The results with 9 observers showed that the minimum length of the line for perceptual filling-in increased systematically as the orientation of the lines changed from the horizontal to the vertical. We suggest that this anisotropy is due to the elliptic shape of the receptive fields of the binocular neurons that contribute to perceptual filling-in at the blind spot.
