Staggerer mutant mice were compared to non-mutant mice in two olfactory learning tasks. It was found that, in spite of a delayed acquisition compared to non-mutants, staggerer mice were able to learn an olfactory habituation task. On the other hand, staggerer presented deficits in an associative olfactory task and, contrary to non-mutants, did not learn this task. Perturbations in olfactory bulbs
