The Lost Mariner (case study)

"The Lost Mariner" is a famous case study of Henry Molaison, who experienced severe memory loss after brain surgery to treat epilepsy. His hippocampus, a brain area crucial for forming new memories, was damaged. As a result, he could no longer remember new experiences or learn new facts, but his short-term memory remained intact. This case helped scientists understand that different parts of the brain are responsible for different types of memory, specifically distinguishing between the ability to hold recent information and the capacity to form long-term memories.
