Theodore Berger of the University of Southern California is developing a prosthesis to restore memory, by replacing a circuit in the brain's hippocampus. Berger described the device at the Global Future 2045 International Congress, held here June 15-16. Already successful in rats and monkeys, the prosthesis is now being tested in humans.
The hippocampus, a brain structure tucked deep in the brain's temporal lobe, converts short-term memories to long-term ones. Epilepsy or other neurological disorders can damage the hippocampus, preventing a person from retaining new memories. [5 Crazy Technologies That Are Revolutionizing Biotech]
