Abstract: This schematic figure shows the estimated size of population receptive fields for 3 retinotopic maps in human visual cortex. Measurements were made with functional magnetic resonance imaging, and data were fit with a compressive spatial summation population receptive field model (Kay et al, 2013, doi:10.1152/jn.00105.2013 ). This figure is adapted from a similar figure made for neural receptive fields in macaque monkey (Figure 1b in Freeman and Simoncelli, 2011, doi:10.1038/nn.2889). Matlab (Mathworks) code was provided by Eero Simoncelli and adapted by Hiroshi Horiguchi and Jonathan Winawer to make this figure. The values used to make the circles were taken from the best fit regression lines in figure 7a of Kay et al, 2013 (doi:10.1152/jn.00105.2013). The radius of the circles are 1 standard deviation of the effective pRF size for a given eccentricity for each area.
