Figure 4.

Correlation and permutation testing. Illustrated for V1 in a single example participant. (A) The difference of beta coefficients between motion conditions (y-axis) and physical stimulus shift conditions (x-axis) for each of the 132 voxels that survived the voxel selection procedure in V1 of this participant. (B) Correlations resulting from repeating this analysis 1,000 times, while shuffling the labels between CLW-M and CCW-M. The unshuffled correlation, illustrated with a solid line, was higher than all but 2 of the shuffled correlations, indicating that the correlation is stronger than what would be expected given the null hypothesis that there is no information shared between the motion and stimulus shift contrasts.
