Abstract

Classical conditioning of the rabbit nictitating membrane(NM) response was accomplished by standard delay procedure of paired tone (CS) and airpuff(US) stimuli. The cerebellar cortex plays a modulatory role in the generationof the conditioned NM response and the development of the learned response of the D-I nuclei at an early stage of learning. With consolidation, the D-I nuclei become free of control from the ccerebellar cortex and serve as the essential component of the memory trace for this model system.

Key words: Nictitating membrane conditioning;Cerebellar cortex;Dentate-interpositus nuclei
