Abstract

The present study was carried out to localize the central nuclei innervating the rat colon using pseudorabies virus-Bartha strain which has been known as a very useful neurotracer. The results were as follows. The central nuclei innervating the proximal colon were premotor area, subfornical organ, preoptic area in telencephalon, and paraventricular nucleus, bed nucleus of stria terminalis, retrochiasmatic area in the diencephalon, and periaqueductal gray, Edinger-Westphal nucleus, tegmental nucleus in the mesencephalon, and parabrachial nucleus, locus ceruleus, A5 area, $K{ddot{o}}lliker$-Fuse nucleus, magnocellular reticular nucleus in the metencephalon, and nucleus tractus solitarius, A1 noradrenergic cell group, dorsal motor nucleus of vagus nerve, nucleus ambiguus, area postrema in the myelencephalon. In the spinal cord, the thoracic division had some nuclei innervating the proximal colon. The nuclei innervating the distal colon were paraventricular nucleus of the diencephalon, Edinger-Westphal nucleus of midbrain, and parabrachial nucleus, locus ceruleus, A5 area, $K{ddot{o}}lliker$-Fuse nucleus, magnocellular reticular nucleus of the metencephalon, and nucleus tractus solitarius, dorsal motor nucleus of vagus nerve, nucleus ambiguus, area postrema in the myelencephalon. In the spinal cord, thoracic, lumbar and sacral division innervated the distal colon.
