Hippocampus Experiment Hippocampus: Background: Henry Moliason (H.M.) began to have major seizures at a young age after a bicycle accident. He was unable to live a normal life because his seizures occurred so often. Procedure: In 1953 William Scoville offered to perform a bilateral medial temporal lobe resection in order to help minimize Moliason's seizures. H.M., at the age of 27, agreed to participate in the experiment. Results: H.M.'s surgery was a major contribution to memory research because it revealed the hippocampus is responsible for explicit and declaritive memory. Moliason was still able to learn motor skills because the surgery had not affected his cerebellum but he did not remember learning them. Doctors at first observed that the surgery was successful and the seizures had been minimized; however, a few days later they observed Moliason was not able to recall eventsthat had just occurred or past events. They also observed he was still able to perform muscle memory or implicit memory tasks. Sources: Squire, L. (2009, January 1). The Legacy of Patient H.M. for Neuroscience.
