Does "free will" actually exist? When we make a decision, how much of it is really our conscious decision and not an imposition from our biology? Or even the consequence of an external stimulus? Neuroscientist Hedi Young explains how the curiosity he had as a child about the perception of color has led him to study how our brain can deceive us. Get ready, your mind is about to be blown away! ? Hedi Young grew up in London and studied biology at Oxford University, before pursuing a career in the BBC as a documentary-maker for several years. Currently, he is a neuroscience PhD student at the Champalimaud Centre for the Unknown, where he conducts research in the Cortical Circuits Lab.
