in experiments on superfused cerebral hemispheric cortex slices of rats preincubated with 3h-gamma aminobutyric acid ( 3h-gaba ) , 3h-serotonin ( 3h-st ) or 3h-noradrenaline ( 3h-na ) it was shown that benzodiazepine tranquillizers ( chlordiazepoxide and diazepam at the concentration of 3 x 10 ( -5 ) m ) fail to change basal and slice electrostimulation-induced release of 3h-gaba , depress presynaptic release of 3h-na and significantly enhance impulse release of 3h-st .
