Supplementary figures show direction preferences of voxels of all observers for the large annulus and two circles experiments. Each figure shows either flat map representations (e.g., Fig. 1B) or pRF locations in the visual field (e.g., Fig. 3). Results are shown separately for each observer and pooled across V1-V3, or separately for each visual area (V1, V2, V3 and MT+) and pooled across observers

Figure S1. Motion direction 
preferences for all observers who 
participated in the large annulus 
experiment, displayed on flattened 
representations of their occipital lobes. 
Dark gray indicates sulci, Light gray, 
gyri. Flat patches have approximate 
radii of 65–85 mm. Color indicates 
phase of each voxel’s fMRI response 
time series, which corresponds to the 
voxel’s motion direction preference 
(see inset). White contours indicate 
boundaries between visual cortical 
areas. Panels for observers O1 and 
O2 are the same as Figs. 1B and C.

Figure S2. Motion direction preferences for all observers who participated in the large annulus 
experiment, visualized as a function of their pRF locations in the visual field. Each panel corresponds 
to a single observer and pooled across V1-V3. Each circle corresponds to a single voxel, the 
coordinates of which represent the center of the voxel’s pRF. Circle size proportional to SNR. Colors 
indicate motion direction preferences (see inset). Dashed lines, horizontal and vertical visual field 
meridians. Pale gray patch, stimulus aperture.

Figure S3. Motion direction preferences for the large annulus experiment, shown separately for each 
visual area, pooled across observers (n = 4). Each panel corresponds to a different visual area. The 
format within each panel is analogous to that in Fig. S2, but the circles correspond to voxels from all 
observers.
