patient HM

• Patient HM, underwent surgery to treat his severe epilepsy, which resulted in the removal of parts of his temporal lobe. This led to a profound impairment in his ability to form new long-term memories, while his short-term memory and other cognitive functions remained relatively unaffected.
• HM's case further supports the multi-store model's differentiation between short-term and long-term memory, as the specific brain lesion disrupted his long-term memory formation while leaving his short- term memory intact.
