This study investigated the impact of benzodiazepine receptor agonist, midazolam and antagonist, flumazenil, on the rat frontal cortex slices oxygen consumption (QO(2)), in presence and absence of gamma-aminobutyric acid (GABA). QO(2) was polarographically determined, using the biological oxygen monitor. As it was previously shown, GABA on its own decreases(More)
The purpose of the present study was to examine the influence of midazolam on the retrieval and acquisition rate of two-way active avoidance in rats. In the schedule 2 x 100 trials, the effects of midazolam (0.5-5.0 mg/kg), benzodiazepine binding site antagonist flumazenil (2.5-10.0 mg/kg), specific antagonist of GABA(A) receptor, bicuculline (0.5-4.0(More)
Physostigmine in a dose of 0.1 mg/kg i.v. expressly stimulated the oxygen uptake in the rat cerebral cortex. This effect was blocked by propranolol and seems be mediated by catecholamines. Since atropine also antagonized the stimulant effect of physostigmine, it appears that the action of physostigmine is primarily cholinergic and that the adrenergic effect(More)
