Abstract

This report describes the distribution of glutamate, GABA and aspartate in the nucleus tractus solitarius (NTS), area postrema, dorsal vagal nucleus and hypoglossal nucleus. Glutamate levels were particularly high in the dorsal, medial and commissural nuclei of the NTS. Section of the IXth and Xth cranial nerves caused a bilateral decrease in glutamate (ipsilateral side = 48%; contralatral side = 36%) and ipsilateral decrease in GABA (27%) in the dorsal and medial NTS. The ipsilateral dorsal vagal nucleus showed a 48% decrease in glutamate and a 30% decrease in GABA after axotomy.
