Difference in learning and retention by Albino Swiss mice. Part III. Effect of some brain stimulants.

According to the two preceding papers, the possible difference in activity of brain stimulants on memory retrieval of "good" and "poor" learning mice was studied. Among the drugs studied, caffeine, oxiracetam and nicotine significantly improved memory recall of poor learning mice. On the contrary, methylphenidate, fipexide and piracetam did not significantly modify memory retention of previously learned avoidance of both poor and good learning mice.
