The muscarinic cholinergic M4 receptor subtype (M4 mAChR) is densely expressed in brain areas known to be involved in the reinforcing effects of drugs of abuse and we were the first to show that mice lacking M4 mAChRs exhibit elevated operant responding for alcohol and reduced capacity to extinguish this alcohol-seeking behaviour. Here we explore possible underlying determinants of this phenotype. We subjected M4 mAChR knockout mice and their littermate wildtype controls to tests of spontaneous activity, learning and memory, nove
