[The effect of piracetam and nicergoline on conditioned-reflex memory under conditions of extreme exposure].
The effects of nicergoline and piracetam on the learning of avoidance response and its restoration after disturbance produced by unexpected changes of the previously established cause-effect relations in experimental environment were studied. It was found that both drugs improve the learning, nicergoline being the most active in the initial period of training, meanwhile piracetam--beginning from the third day. The drugs prevent disturbance of the avoidance response but piracetam is more effective.
