Involvement of dorsal hippocampus glutamatergic and nitrergic neurotransmission in autonomic responses evoked by acute restraint stress in rats

Highlights • NMDA receptor into the dorsal hippocampus mediated autonomic responses to stress. • Stress-evoked increase in nitrite and nitrate concentrations in the dorsal hippocampus. • Nitrergic system in the dorsal hippocampus mediates responses caused by stress.
