Abstract
The consummatory behavior of normal rats and rats with lesions of the hippocampus, neocortex, entorhinal cortex or transections of the fornix was compared during 3 days of ad-lib feeding. The results showed that none of the groups differed on the mean amount of food or water consumed. However, the rats with lesions of the hippocampus dropped a significantly larger portion of their food ration through the wire mesh floors of the cages. The results are discussed in terms of a possible confounding which could occur when rats with hippocampal lesions are maintained on fixed rations of food and housed in wire mesh cages.
