The Placebo Experiment

Could the power of fake pills be used to treat some of our most common medical complaints? To find out, Dr Michael Mosley embarks on Britain's largest ever trial to investigate the placebo effect. He is heading to Blackpool to gather 117 people suffering from backache - one of the leading types of chronic pain - before trying to treat them with nothing but fake pills and the power of the mind. Working with experts from the University of Oxford, Michael discovers that the placebo effect is more than just a medical curiosity. The brain is actually capable of producing its own drugs, and these can be more powerful than prescription painkillers. Michael's volunteers come from all walks of life, but they have all suffered with bad backs for years and feel their conventional medication isn't up to the job. They include Stacey, who is struggling to keep up with her two energetic daughters, wheelchair user Jim, who longs to be able to get back on a boat, and poker player Moyra, who is looking for a painkiller which doesn't affect her performance. They think they are taking part in the trial of a powerful new painkiller, but their blue and white capsules actually contain nothing but ground-up rice. Can this fake treatment make a real difference? And how will the volunteers react when Michael reveals the truth? Michael also finds out about some remarkable placebo experiments from around the world, including a woman in Oxfordshire who experienced a near-miraculous recovery after undergoing fake surgery to fix her chronic shoulder pain. Plus a team in Lancashire who want to see if the placebo effect can cure a broken heart. And Michael discovers a team in Germany working on a placebo that works even if you know you are taking it, which might improve the lives of transplant patients. Michael also tests this out on himself - attempting to train his own body to respond to a fake treatment - a foul-tasting green drink - as if he were taking actual drugs.

Who is in Control

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 3: Who is in Control ‘Who Is in Control?’ explores the great deception that greets us each morning when we awake: it feels as though we are in conscious control of our lives but the truth is that we are not. Instead almost every action, every decision, every belief that we hold is driven by parts of the brain that we have no access to.

Invasion of the Brain Snatchers

We like to believe we’re in control. But if what we’re discovering about parasites is anything to go by, who is really in control is a lot more complicated, and a lot more interesting, than we ever imagined. So let “The Nature of Things with David Suzuki” help you get over the ick factor, and explore the world of parasites. So let “The Nature of Things with David Suzuki” help you get over the ick factor, and explore the world of parasites. Scientists have collected hundreds of examples of parasites that brainwash their hosts. And now researchers are starting to untangle these parasites’ evolutionary tricks of the trade. In the coastal estuaries of California, Professor Kevin Lafferty of the United States Geological Survey introduces us to a flatworm that lives in three hosts - a snail, a fish and a bird. This parasite’s influence is so profound that it tips the balance of the local ecosystem

Can Our Minds Be Hacked?

Our minds store our entire lives, our memories and our deepest desires. Tell no one, and our thoughts remain our own. But our brains are biological computers. Computer hackers can tamper with our email. Could brain hackers someday be able to rewrite our thoughts?
