The Brain

Scientists have been studying the brain for centuries, but its trillions of neuronal connections make it extraordinarily complicated, and each new advance seems to reveal another layer of complexity. MGH researchers are compiling thousands of brain images to gauge what goes awry in psychiatric and neurological disorders and to probe how particular genes affect behavior. They’re observing the brain under general anesthesia to make surgery safer and to explore what happens when consciousness is lost; experimenting with enzymes involved in Alzheimer’s disease that could be targets for drug treatments; and creating microelectrodes that could treat epilepsy and help the severely depressed.
