[Inhibitory effect of scopolamine on recent memory of mice].

In this research the Authors have studied the action of scopolamine on the memorization of the explorative behavior of the mice. They gave scopolamine before each of the 2 explorations made at an interval of 24 h one from the other. The results obtained show that in these experimental conditions, scopolamine cancels the short-time memory in a more complete fashion compared to the only administration before the second exploration. The Authors advance the hypothesis that this effect of scopolamine can be in relationship to its action on the cholinergic system.
