Microinfusions of EAA antagonists (APV 0.1 microliter 25 mM, gamma-DGG 0.1 microliter 50 mM, CNQX 0.1 microliter 50 mM, ketamine 0.1 microliter 0.2 M) were performed in freely moving rats while recording the long latency jaw opening reflex (JOR) elicited by electrical stimulation of the dental pulp. NMDA and non-NMDA antagonists were applied in the trigeminal sensory complex at the termination of dental pulp afferents. The selective NMDA antagonist APV strongly reduced the amplitude of the… CONTINUE READING
