Abstract:
Lesions of the medial pallium in toads significantly retarded extinction of a water-reinforced instrumental response in a runway training situation, relative to sham-operated and intact controls. The lesion had no effect on acquisition or in the amount of water uptake during acquisition. The results suggest that the medial pallium of toads plays a role in response inhibition. This possibility is discussed in relation to the results of analogous experiments with hippocampectomized rats.
