Abstract:
By means of substance P receptor (SPR) immunofluorescence histochemistry combined with Fluoro-Gold fluorescent retrograde labeling, SPR-like immunoreactive neurons in the caudal subnucleus of the spinal trigeminal nucleus of the rat were observed to send their axons to the nucleus of Kölliker-Fuse and ventrolateral part of the lateral parabrachial nucleus bilaterally with a clear ipsilateral dominance. These neurons were distributed mainly in lamina I, and additionally in lamina III.
