Cells of origin of pathways descending to the spinal cord in a lizard (Larcerta galloti).
The pathways descending to the spinal cord have been studied in the lizard Lacerta galloti with the HRP-technique. Cells of origin of such pathways have been demonstrated in the hypothalamus and throughout the brain stem. In the brain stem, besides labeled cell groups in the reticular formation and in the vestibular nuclear complex, labeled neurons have been found in the nucleus ruber, in the locus coeruleus, in the two deep cerebellar nuclei, in two somatosensory relay nuclei (the nucleus funiculi dorsalis and the descending nucleus of the trigeminus) and in two presumably parasympathetic nuclei (the nucleus of Edinger-Westphal and the dorsal motor nucleus of the vagus).
