Abstract

In comparison with neocortically ablated animals, the hippocampally ablated animals were severely impaired in position reversal and single alternation learning. The hippocampally ablated animals showed less flexibility of solutions as revealed in the decreased number of different paths chosen and the decreased number of shifts in a Dashiell maze. With respect to response shift the cortically ablated and sham-operated animals manifested an obvious tendency to avoid the preceding forced turns while the hippocampally ablated animals were found to perseverate. These results suggest that hippocampal ablation produced an obvious tendency toward response perseveration.
