A, Case 92. PRV-immunoreactive neurons at the injection site in the lateral thalamus; the center of the injection site is 520 μm from the medial border of the ventroposterolateral nucleus (VPL). The survival time was 72 hr. B, Case 89. PRV-immunoreactive neurons at the injection site in the lateral thalamus; the center of the injection site is 320 μm from the medial border of the VPL nucleus. The survival time was 77 hr. Reticular nucleus of the thalamus (Rt); ventroposteromedial nucleus (VPM). C, Case 92. Retrogradely labeled PRV neurons in the caudal medulla, at the same level as in Figure 3C, are present in the medial trigeminal nucleus caudalis (TNC) only. D, Case 89. Retrogradely labeled PRV-immunoreactive neurons in the caudal medulla are present in both the gracile nucleus (Gr;arrowhead) and in the medial part of the trigeminal nucleus caudalis (TNC; arrow). Cuneate nucleus (Cu). Scale bar: 300 μm.
