Confirmation of the injection sites by accumulation of retrograde tracer into the spinal trigeminal nucleus caudalis (Sp5C), which sends ascending fibers to the elPB. A, Representative photomicrographs of bright field (top) and fluorescent (bottom) images in the boxed area shown in B. Note that the injected retrograde tracer (1.25% FluoSpheres) accumulates in the superficial layer of the Sp5C 4 days after the injection, indicating that the site of injection receives projections from this region (scale bar = 100 μm). Sp5C, spinal trigeminal nucleus, caudal part; sp5, spinal trigeminal tract. B, Atlas corresponding to the same antero-posterior level as in A from Franklin and Paxinos [15].
