Localization of spinal cord preganglionic neurons innervating the superior cervical ganglion in the golden hamster.
The retrograde neuronal tracer Fluoro-Gold (FG) was used to determine the location and distribution of preganglionic sympathetic neurons in the spinal cord of the golden hamster. FG was injected unilaterally into the superior cervical ganglia. Labeled neurons were found only ipsilateral to the injection site in segments C8 to T5 of which the segments T1 to T3 contained about 98% of the labeled cells. Neurons were found in four regions of the spinal cord: the intermediolateral nucleus (43%), the lateral funiculus (55%), the central autonomic area (1%) and the intercalated region (less than 1%). In the intermediolateral nucleus, cells often were arranged in clusters of which several were seen in each spinal segment.
