The effects of cerebellar lesions on a classically conditioned eyeblink response was examined using Dutch Belted rabbits as subjects. Results confirmed our previous findings, using New Zealand White rabbits, that cerebellar cortical lesions do not abolish conditioned responding if the interpositus is intact. However, unlike our previous studies using New Zealand White rabbits, Dutch Belted rabbits failed to reach a pre-lesion level of performance. These results suggest a possible important strain difference in this paradigm.
