A Deviation of preferred orientation from ideal vertical (blue), cardinal (green), and radial (orange) maps, as a function of pRF eccentricity (left) and pRF angle (right). B Deviation from vertical minus deviation from radial, as a function of pRF eccentricity (left) and pRF angle (right). Gray lines, individual subjects. Orange points, significantly lower deviation from radial than from vertical (p < 0.05, one-way t-test, seven degrees of freedom, no correction for multiple comparisons). C Deviation from cardinal minus deviation from radial as a function of pRF eccentricity (left) and pRF angle (right). Gray lines, individual subjects. Orange points, significantly lower deviation from radial than from cardinal (p < 0.05, one-way t-test, seven degrees of freedom, no correction for multiple comparisons). D Deviation from radial as a function of angular distance from the closest meridian. E pRF R2 as a function of angular distance from the meridian.
