From: Dopamine D2receptors mediate two-odor discrimination and reversal learning in C57BL/6 mice
Wild-type and D2R-deficient mice perform the digging task equally well. No differences in responding as a function of genotype were found, and similar latencies to retrieve the reinforcer were seen. These response patterns suggest that the training from the previous day influenced behavior, demonstrating that both genotypes are capable of learning and retaining goal-directed behaviors.
