The effects of hippocampal ablation on some forms of response inhibition associated with nonreinforcement or delay of reinforcement were investigated in the rat. In the first experiment, hippocampal ablation restored the preoperatively extinguished bar-pressing response to a significant degree. In the second experiment, hippocampally ablated animals responded more frequently than did the neocortically ablated animals during the extinction of a differential barpressing response. In the third experiment, hippocampal ablation increased the rate of bar pressing to negative stimuli without affecting the response rate to positive stimuli. In the final experiment, the decremental change in runway performance due to the delay of reinforcement was much slighter in the hippocampally ablated animals than in the neocortically ablated animals.These results suggest that the hippocampus is important for the inhibitory control of operant behavior
