HBM_21200_sm_suppinfofig1.tif13560KSupplemental Figure S1. Locations of retinotopic areas, V1d/v, V2d/v, V3d/v, V3A, V3B, V7, hV4, V4v, V8, LOc, and MT+, in one subject's (S1) hemispheres and their relationship to visual field representation (up to 16° eccentricities), and motion-responsive regions of the visual cortex. Data on the left and right hemispheres are shown in the left and right regions of the figure, respectively. The colored lines on the inflated cortices indicate each area's border by the color code below A and B. Note the overlap of hV4, V4v, and V8 in the ventral occipital cortex. We adopted two different parcellation schemes in this region: one consisting of V4v and V8, the other is hV4 alone. We created probability and entropy maps independently for each schema. (A, B, C, and D) Angular visual field representation measured by the phase-encoding retinotopy experiment. A and C display the entire data of the visual cortex, while B and D zoom in on the posterior ventral region to better visualize the angular representation near areas hV4, V4v and V8. The color overlay on the cortex indicates the preferred stimulus angle at each cortical point by the color code to the right of A or C. The more saturated the color, the higher the statistical significance of retinotopic activity, as shown in the rainbow-like color bar. (E, F, G, and H) Eccentricity visual field representation measured by the phase-encoding retinotopy experiment. The data is presented in the same format as A, B, C, and D. (I and L) Field sign map computed from the angular and eccentricity maps. The blue code indicates mirror-image representation, while the yellow indicates non-mirror-image representation. The more the color is saturated, the stronger the degree of the mirror- or non-mirror-image (see the color bar on the bottom). (J and M) Foveal or peripheral representation measured by the experiment using the standard block paradigm. The yellow region indicates fMRI activity evoked by foveal stimulation, while the blue indicates activity by peripheral (16°) stimulation (see the color bar at the bottom). (K and N) Motion-sensitive regions. The yellow region indicates fMRI activity evoked by the expanding motion of a low contrast concentric grading (see the color bar at the bottom).
HBM_21200_sm_suppinfofig2.tif514KSupplemental Figure S2. Inconsistency in the locations of the visual areas among different hemispheres after surface-based registration. This figure shows the data for the hV4 model. Other details are consistent with those in Fig. 3. The average probability over the 11 retinotopic areas was 0.279 (SD: 0.074).
HBM_21200_sm_suppinfofig3.tif936KSupplemental Figure S3. Uncertainty regarding which visual area is located at each anatomical point after surface-based registration. This figure shows the data for the hV4 model. Other details are consistent with those in Fig. 4. The average entropy over the 11 visual areas was 1.14 bits (SD: 0.2).
