In this magazine we explore how scientists and doctors use imaging and other techniques to understand what is going on inside the brain without having to open the skull. These techniques include magnetic resonance imaging (MRI), computed tomography (CT) and positron emission tomography (PET). Also featured are case studies on the ethical, social and legal issues around the brain, and interviews with a young woman being treated for obsessive-compulsive disorder, a paediatric brain surgeon and a cultural historian interested in the brain. A related poster is available (also on TES).
