Figure 8From: NAAG peptidase inhibition in the periaqueductal gray and rostral ventromedial medulla reduces flinching in the formalin model of inflammation Reaction times of rats placed on a 52.5°C surface following injection of NAAG peptidase inhibitor into the PAG and RVM. Baseline latencies (O time) were established from 3 pretrial tests per animal and reaction times were assessed at different intervals after administration of saline or 150 μg ZJ43 into the PAG (n = 4, 6) and RVM (n = 4, 4).Back to article page
