Bilateral administration of NMDA (5 x 10(-10) mol) in the substantia nigra pars compacta increases the striatal dopamine (DA) release. However, this enhancing effect of NMDA was suppressed by nitrous oxide exposure at 0.1 MPa, which induced per se a decrease of the DA release. These results show that nitrous oxide exerts a reversal effect on the increase in(More)
To test the hypothesis that stress alters the performance of the respiratory control system, we compared the acute (20 min) responses to moderate hypoxia and hypercapnia of rats previously subjected to immobilization stress (90 min/day) with responses of control animals. Ventilatory measurements were performed on awake rats using whole body plethysmography.(More)
