  1. PC = Principal component. R = right, L = left hemisphere. PC load denotes positive (+) or negative (-) correlation of voxels at the given coordinates with the PC
  2. *Norm-SSD: normal volunteers during somatosensory discrimination (SSD); Patients-SSD: patients during the same condition, unpaired t-test in PC expression coefficient.
