Unformatted text preview: Electrolytic lesions-contingency degradation Experiment 2: NMDA lesions-contingency degradation Experiment 3: both lesions-contingency degradation and retrained for devaluation Experiment 4: NMDA lesion of the retrohippocampus Experiment 5: Disconnection procedure-electrolytic lesion to dorsal hippocampus-excitotoxic to entorhinal cortex and subiculum. Results: Experiment 1: prevented learning Experiment 2: no effect Experiment 3: degradation-same as experiments 1 and 2. Devaluation-no effect. Experiment 4: had an effect Experiment 5: Entorhinal cortex-had an effect. Subiculum-no effect. Conclusion: Main input if from Entorhinal cortex and when you lesion this you prevent learning. Electrolytic lesions prevent learning. Critique: They switched subjects during the experiment; using different genders allows for less control in the experiment and there could have been hormonal issues that played into the results because of this....
