Initial Localization of the Acoustic Conditioned Stimulus Projection System to the Cerebellum Essential for Classical Eyelid Conditioning

Previous experiments have demonstrated a sufficient and necessary involvement of mossy fibers in projecting conditioned stimulus information to the cerebellum during classical eyelid conditioning in rabbits. Presented here are electrophysiological, anatomical, and lesion data that suggest that cells within the lateral pontine nuclear region may be essentially involved in projecting information concerning the occurrence of acoustic conditioned stimuli to the cerebellum during classical conditioning.
