In 1953, a patient named Henry Molaison had a surgery and removed his _____ to treat his epilepsy.

Understand the Problem

The question is asking about the part of the brain that was surgically removed from patient Henry Molaison (often referred to as H.M.), which resulted in his inability to form new memories while retaining memories from the past.

More Information

Henry Molaison, known as H.M., had his hippocampus removed in an attempt to treat his epilepsy. This surgery alleviated his seizures but resulted in severe anterograde amnesia, where he could not form new long-term memories.

Tips

A common mistake is confusing the role of the hippocampus with other brain areas. The hippocampus is crucial for forming new memories.
