What new methods of analysis have been developed in the age-old struggle to discover if someone is telling the truth...or not? Some scientists have gone beyond the polygraph to model other ways of detecting whether we are getting a straight answer or being led down a crooked path.
After millennia of speculation about what goes on inside the human brain, we now have the tools to explore its hidden reaches. These tools are leading to research that may help those suffering from afflictions such as epilepsy and Alzheimer's disease. They are also shedding light on the mystery of consciousness and what makes us who we are.
Horizon follows the story of Richard Gray and his remarkable recovery from a life-changing catastrophic stroke. The film shows the rarely seen journey back to recovery. Recorded by his documentary film-maker wife Fiona over four years, this film shows the hard work of recovery. Initially bed bound and unable to do anything, including speak, the initial outlook was bleak, yet occasionally small glimmers of hope emerged. Armed always with her camera, Fiona captures the moment Richard moves his fingers for the first time, and then over months she documents his struggle to relearn how to walk again. The story also features poignant footage delivered in a series of flashbacks, in which we see and hear Richard at his professional best. He was a peacekeeper with the United Nations, immersed in the brutal war in Sarajevo, Bosnia. We also hear from the surgeons and clinicians who were integral to Richard's remarkable recovery, from describing life-saving, high-risk reconstructive surgery to intensive rehabilitation programmes that push the former soldier to his limits.
Part 1 of this eight-part series of shorts introduces the world of the visual scientist. Beyond boggling your mind, Prof. Arthur Shapiro explains how and why you see what you see -- and what part of what you see is actually "real", as opposed to how your mind fills in the blanks.
How much of the sensations we feel is determined by our physical bodies? Maybe our minds play a bigger role than we know. I’ll see if people can be tricked into feeling intense physical pain, even though it’s all in their heads. I’ll also look at a machine that makes it possible for you to tickle yourself, and I’ll show you a weird physical illusion you can do at home.
Neuroscientist David Eagleman explores the human brain in an epic series that reveals the ultimate story of us, why we feel and think the things we do. This ambitious project blends science with innovative visual effects and compelling personal stories, and addresses some big questions. By understanding the human brain, we can come close to understanding humanity. Part 4: How Do I Decide The human brain is the most complex object we’ve discovered in the universe, and every day much of its neural circuitry is taken up with the tens of thousands of decisions we need to make. ‘How do I decide?’ is a journey through the unseen world of decisions, and how they get made.
