Relationship between the population spatial frequency tuning (pSFT) bandwidth and retinotopic eccentricity. A: bandwidth increases slightly with eccentricity in V1. Each point illustrates a voxel. Data from every single subject has been displayed with a certain color. B: average of the mean pSFT bandwidth within each eccentricity bin, across subjects. Error bars show means ± SE. C: distributions of the correlation coefficients between bandwidth and eccentricity, estimated per subject. Coefficients are significantly different than zero in all three areas (*P < 0.05; **P < 0.001).
