Gene found to be crucial for formation of certain brain circuitry

Using a powerful gene-hunting technique for the first time in mammalian brain cells, researchers report on a gene involved in building the circuitry that relays signals through the brain. The gene is a likely player in the aging process, the researchers say. Additionally, in demonstrating the usefulness of the new method, the discovery paves the way for faster progress toward identifying genes involved in complex mental illnesses such as autism and schizophrenia — as well as potential drugs for such conditions.
