It was shown in experiments on rats that the selective blocker of GABA receptors bicuculline (2 mg/kg) does not decrease the activating effect of diazepam as to the reaction of self-stimulation. The GABA-mimetic muscimol (0.5 and 1 mg/kg) had no effect on self-stimulation rate, while in the dose of 2 mg/kg causing behavioral changes produced a powerful decrease in it (by 93.3%). During the combined administration of diazepam and muscimol (1 mg/kg and 0.5 mg/kg, respectively) no potentiation of diazepam effect was observed. It is suggested that diazepam-induced facilitation of the reaction of self-stimulation is not due to the alteration in the activity of GABA-ergic processes.
