Table 1: Shows the range of activations represented by the number of statistically significant voxels during stimulation by the black-white (BW) and yellow-blue (YB) checkered patterns The next two columns show the statistically significant differences between BW and YB stimulations, again expressed by the number of voxels (with tested hypothesis being BW>YB and YB>BW resp.). The last two columns show the percentage difference in the number of activated voxels of the statistical difference.
