The brain receives lots of sensory information and must choose what to focus on and ignore. Many neurological disorders—including schizophrenia, autism, and attention deficit hyperactivity disorder—involve problems concentrating and ignoring distractions. Scientists have long believed that a brain region called the prefrontal cortex (PFC) selects what information to focus on. The neocortex, the brain’s outermost layer, is found only in mammals and is responsible for humans’ ability to recognize patterns.
