Figure 2. Continuity of labeling across thalamic targets.
Each panel shows the enhancement of MR signals in presumptive VPL and Po across a series of slices 100 μm thick, spaced 200 μm apart. Rt and VM are included at the margins of this slice series. A) The average of 24 T1-IR scans, acquired during one scan session, from a single ex vivo case. B) An average of 9 T1-W scans in vivo, across 3 scan sessions. C) The same slices as in panel B, after normalization, co-registration and subtraction of baseline images. Voxels showing significant enhancement (p < 0.002, uncorrected) are shown in red. Intrinsic midline enhancement is the fornix, a white matter tract.
