Comparison of COR between pseudo-low and pseudo-high resolution images. a–c Representative original and rescaled images. The b original images (30 × 30 pixels) were a downscaled (final size, 15 × 15 pixels) to produce pseudo-low resolution images, and c upscaled (final size, 60 × 60 pixels) to produce pseudo-high resolution images. d–f Curves of mean COR as a function of distance d when θ = 135 are shown for the e original, d pseudo-low resolution, and f pseudo-high resolution images. Data are means ± SEM (n = 10 animals in each age group; orientation of the worms is 0°)
