Response Perseveration Following the Hippocampal Ablation in the Rat
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…
Chlordiazepoxide and Food Intake in the Rat
The effect of chlordiazepoxide on food intake in the rat was studied under a variety of conditions. Administration of chlordiazepoxide (5mg/kg) produced an increase in food intake during a 2 hr feeding period up to 5 hr intervention after an intraperitoneal injection. A marked increase in food intake was observed during 10 daily injections of 5mg/kg chlordiazepoxide. Under the satiated condition an elevation of food intake by chlordiazepoxide was…
The Effects of Hippocampal Ablation on the Inhibitory Control of Operant Behavior in the Rat
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 di…
