Sagittal knife cuts were made interrupting efferent projections of either the rostral or the caudal trigeminal nuclear complex in the rat. Only rostral cuts resulted in significant, specific deficits in ipsilateral facial nociception. These results are not consistent with a well-known view which emphasizes only caudal nuclear projections as critical for orofacial pain.
