Subcortical Storage of Classical Conditioning

MANY investigators1–5 have emphasized the importance of the cerebral cortex in instrumental learning. They were able to demonstrate lateralization of learning to one cortical hemisphere using spreading depression as a technique of functional decortication. Bureš, Burešová and Fifková6, however, reported a failure to lateralize the effects of learning a passive avoidance response to one hemisphere, and attributed this failure to the possibility that such learning was a type of emotional conditioning involving predominantly subcortical mechanisms.
