Receptive field size as a function of eccentricity. a Scatter plots of footprint sizes as a function of eccentricity, for LGN (square symbols, top row) and PGN (circular symbols, middle row) for either on, off, the dominant, or both stimulus polarities. Note the dominant footprint was on or off, whichever had the larger magnitude, and the combined footprint was the union of the on and off regions. Footprint sizes in the LGN vs. PGN (bottom row) increase with increasing eccentricity (binned at 5° intervals); the square (LGN) or circular (PGN) symbols in each bin mark the mean, the wide pale bars associated with the symbols denote the quartiles, and the lines indicate extreme values. b, c A direct comparison of combined (b) and dominant (c) footprint sizes for PGN (ordinate) vs. LGN (abscissa) across eccentricities; the line of unity slope is in gray; conventions as in (a). The footprints were calculated with a threshold of q = 0.01; see Supplementary Fig. 2 for footprints calculated with more relaxed or more stringent thresholds
