Hunger Hormone Linked To Memory

The hormone that controls the body's hunger pangs may also boost the memory, according to Scottish scientists. Researchers at Dundee University have found a link between the hormone leptin and the brain's memory and learning process. Leptin controls food intake and body weight and staves off the urge to eat. The study was carried out by a team which specialises in the braincell processes that produce learning and memory. Jenni Harvey, one of the researchers, said: "The hormone leptin, which is known to control food intake and body weight, has been shown to exert a profound influence on learning and memory processes in a region of the brain called the hippocampus.
