Comparison of cell array acuity to psychophysically measured photopic spatial acuity. A, Acuity of OFF-midget ganglion cell and OFF-midget bipolar cell arrays compared with two measures of human achromatic grating acuity [Anderson et al., 1991 (diamond symbols); Wilkinson et al., 2016 (triangle symbols)] across the eccentricity range 5–30°. Note the close correspondence of OFF-midget ganglion cell array acuity to the psychophysical measures. B, Comparison with OFF-DB cell (combined DB3a and DB3b) and parasol ganglion cell array acuity with the same psychophysical data. Note that parasol cell array acuity falls well below human acuity at all eccentricities.
