Preganglionic inputs to the stellate ganglion of the cat during postnatal ontogenesis.
The localization of preganglionic neurons forming, connections with the stellate ganglion was studied using a method based on retrograde axonal transport of horseradish peroxidase in cats during postnatal ontogenesis from birth to six months of life. The number of preganglionic neurons and spinal cord segments connected to the ganglion increased from birth to 10 days of age, and then decreased. The proportion of preganglionic neurons in different spinal cord nuclei changed during life and became comparable with that in adults by age six months. This was accompanied by an increase in the proportion of cells in the nucleus intermediolateralis thoracolumbaris pars principalis, with a decrease in the number of neurons in the nucleus intermediolateralis thoracolumbaris parts funicularis and in the ventral horns of the spinal cord.
