Fig. 1.

Representative probabilistic distributions of each tract and regions of interest (ROI) used as seed and termination regions for each tract, rendered on fractional anisotropy maps. Intrainsular tract (top, red-orange) was seeded from the posterior insula (green) to the anterior insula (blue). The thalamocortical tract (bottom, blue-light blue) was seeded from the ventral posterolateral nucleus of the thalamus (VPL, yellow) to primary somatosensory cortex (SI, white)
