Robert Winston hosts a three-part survey of how the brain builds a mind, moving from infancy to old age through case studies, brain scans, and hands-on demonstrations. One episode follows how children learn language and recognize faces almost from birth, using experiments with babies to show pattern recognition developing in real time. Another turns to memory and personality, tracking patients whose injuries or illnesses have altered who they are, including people who have lost the ability to form new memories or who describe sudden shifts in temperament after brain damage. Winston talks with neuroscientists and psychologists who explain what brain imaging can and cannot tell us, and the series uses their research to ask how much of identity is fixed at birth versus shaped by experience. Reenactments and laboratory footage sit alongside the interviews, keeping the science grounded in specific, observable behavior rather than abstraction. It plays as an accessible primer on cognition for viewers with no scientific background.
