Figure 3. Systematic maps of curvature degree.

(A) Maps of different curvature degrees. Each map is one curvature minus average of all straight gratings (Case 1). 1–6 and 7–12: upwards and downwards curvatures, respectively, from low to high curvature preference, 13: straight grating. Red dotted square marks the region that is further analyzed in Figure 7A,B. Correlation values for pairs of curvature response maps (from A). Color bar: high (red) to low (blue) correlation values. (C) The more similar the curvature the greater the correlation value. X axis: curvature degree difference. Y axis: correlation value. Color symbols: correlation value for each curvature above with respect to its curvature degree distances (each fit with matching color line; regression values are shown on the right). The fitted lines are not meant to indicate linear fits; rather, they help to see the trends. Scale bar, 1 mm.

These values are provided to give reader an idea of what high map correlations values are. When results from different runs are compared, only maps of similar orientation have high (orange, yellow) correlation values, while non-matching orientations produce low (blue) values. Color bar: correlation values (high, red, to low, blue) for pairs of maps. Note that negative values often occur for orthogonal orientations and are weaker in magnitude than positive values.

(A) Case 2: Maps of different curvature degrees. (B) Correlation values for pairs of curvature response maps (from A). The more similar the curvature, the greater the correlation value (from B). (C) Case 1: Imaging maps of different curvature orientations. (D) Correlation values for pairs of curvature response maps (from C). Curvatures with the same orientation have greater correlation values (from D). Error bar: SEM. Scale bar: 1 mm. The correlation values are calculated based on the full data set (n=30 trials).
