Abstract

MANY workers have demonstrated the use of spreading cortical depression to lateralize the effects of conditioning to one cerebral hemisphere. Russell and Ochs1 have shown that food-reinforced bar-pressing lateralized to one hemisphere could be transferred to the other hemisphere with a single reinforced trial during bilateral cortical function. More recently Russell and Ochs2 showed that a necessary condition for such one-trial inter-hemispheric transfer of a memory trace was the presence of reinforcement during bilateral function. If animals were allowed to perform the conditioned response in the absence of reinforcement no transfer was found.
