Fig. 3: Orientation preference changes smoothly across visual space and V1.
From: Natural scene sampling reveals reliable coarse-scale orientation tuning in human V1
A Orientation preferences are plotted in visual space. Each line represents a single voxel and is positioned at the voxel’s pRF center. Hue and orientation of the line indicate the preferred orientation. Line length, width, and scale reflect the amount of variance (R2) explained by the constrained model. A solid square at ±4.2 deg indicates the size of the natural scene stimuli. See also individual subject plots in Supplemental Fig. S1. B Orientation and pRF polar angle map overlaid on the left and right inflated “fsaverage” surfaces. For the angle map and unthresholded orientation map, all vertices in V1, V2, V3, and V4 are plotted. For the thresholded orientation map, only vertices with the top 50% full model R2 are plotted. See also individual subject maps in Supplemental Fig. S2.
