Clusters > 20 were included in analysis with threshold set at P < 0.001, uncorrected P-values presented.

^aExperimental treatments include AR (n = 29) and SR (n = 10) groups.

^bMissing cluster value is contiguous with voxel cluster listed immediately above and represents 1 of 2 continuous voxel clusters with 2 different center voxels.
