[The effect of nooglutil and piracetam on different forms of operant learning]

We studied effects of a new drug with nootropic action nooglutil (N-(5-hydroxynicotinoil)-L-glutaminic acid, OHK-10) on initial stages of different forms of operant behaviour in rats, namely avoidance learning in Shuttle box, in Skinner box and on T-maze reflex with water reward. Comparing dates resulted from these three methods permitted evaluation of effects of the drugs on learning. Both drugs had no effects on avoidance response in shuttle box and T-maze reflex with water reward. Nooglutil enhanced escape and avoidance responses meanwhile piracetam improved only escape response.
