It has been shown that blockade of muscarinic receptors of the anterior striatum (AS) induces significant impairments in the retrieval of stored information of a passive avoidance task, trained with conventional parameters of footshock, and that the same blockade is ineffective in altering short-term memory of this task. The results of the present experimental series showed that in conditions of over-reinforcement, microinjections of scopolamine into the AS shortly after training or before retention testing of passive avoidance, do not produce memory deficits when retention is assessed 30 min, 24 h or 48 h after training. It is suggested that after an enhanced learning experience (over-reinforcement) striatal cholinergic activity is not involved in short- and long-term memory functions.
