EFFECT OF INTRODUCTION OF BLIND ALLEYS ON MAZE PERFORMANCE OF RATS WITH HIPPOCAMPAL LESIONS

Forced 9 rats with lesions in the hippocampus and 9 controls with neocortical lesions to run the correct pathway in a multiple U maze by having the blind alleys blocked at the choice points. After asymptotic running speeds were reached, the blind alleys were opened. The experimental Ss were more distracted than the controls by the introduction of the blinds when the blind alleys and correct alleys were similar. When the blind alleys and correct alleys were made distinctively different, their introduction did not differentially affect the groups.
