The authors have previously demonstrated that Purkinje cell-degeneration (pcd) mutant mice are impaired in eyeblink conditioning (L. Chen et al., 1996a). The present study addresses the following 3 questions: (a) whether pcd mice perceive the conditioned and unconditioned stimuli as well as the wild-type mice, (b) whether pcd mice have a normal sensitization level, and (c) whether the residual learning in pcd mice is cerebellum-dependent. Results indicated that the pcd mice exhibited normal tone-induced responses in the cochlear nucleus and normal sensitivity to heat-induced pain. They showed a similar level of sensitization as the wild-type mice and were completely unable to learn conditioned eyeblinks after bilateral lesions aimed at the anterior interpositus nucleus. Thus, pcd mice are partially impaired in eyeblink conditioning because of a deficiency in learning mechanisms, and the residual learning in the pcd mice is mediated by the cerebellar nuclei.
