Fig. S3.

Voxelwise context preferences exhibit relatively fine-scaled spatial interdigitation. Black lines show the mean-squared error predicting the preference in ROI voxels by the average of the preferences at the specified radius. Gray bands show the 95% prediction interval from a permutation test where we randomly shuffled voxel preferences. Plots are scaled relative to the mean of the null distribution for ease of visual comparison. The vertical line shows the first point at which the observed error is larger than the error in the null distribution. Significantly lower error before this point provides evidence of spatial clustering, whereas significantly higher error after this point provides evidence of spatial interdigitation. Each plot shows data from one subject, and subjects are ordered by decoding accuracy.
