In order to clarify the roles of hippocampal M1 and M2 muscarinic receptors in working and reference memory performance of rats, the effects of intrahippocampal injections of selective antagonists at both receptors on this behavior were examined with a three-panel runway task. In the working memory task, the M1 muscarinic receptor antagonist pirenzepine… CONTINUE READING
