Summer research briefs: Brain power

Molding memories Some people find it hard to remember what they had for lunch yesterday, while others can remember every detail of the house they grew up in. Understanding how memories are retained and recalled has always intrigued researchers, especially when seeking therapeutics for neurodegenerative diseases like Alzheimer’s. Researchers speculate […]

In 1953, Henry Molaison underwent an experimental surgery known as bilateral temporal lobectomy to treat the severe epilepsy he had been experiencing. His surgeon removed his medial temporal lobe, including a structure known as the hippocampus—a part of the brain involved in the storage of long-term memory—in hopes of curing […]
