[Representation of afferent nerves from the concha auriioulae in the caudal nucleus of the trigeminal system].
It was shown in acute experiments cn cats that the auricular trigeminal nerve consists of A8 group fibers. Threshold electric stimulation of the nerve activates the fibers of the dorsal and ventral trigeminal tracks and neurons of the caudate nucleus at the level 3 mm caudal to the obex. Neuronal units of paramedian and lateral reticular nuclei can be activated by electric stimulation of the fibers of the auricular trigeminal nerve that is adequate to both noxious and non-noxious types of stimulation.
