Pleasure is vital for our survival - without it we wouldn't eat or have sex, and would soon die out as a species. But how does pleasure work and what gives us the most pleasure in life?
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.

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.
In part 3, Prof. Shapiro shows us that the brain is challenged to process some stimuli from the eyes and sometimes "guesses" what you are seeing. Join him as he takes us through visual perception challenges like the "Curveball Illusion". Has he thrown you for a loop yet?
It is a feeling we all know - the moment when a light goes on in your head. In a sudden flash of inspiration, a new idea is born. Today, scientists are using some unusual techniques to try to work out how these moments of creativity - whether big, small or life-changing - come about. They have devised a series of puzzles and brainteasers to draw out our creative behaviour, while the very latest neuroimaging technology means researchers can actually peer inside our brains and witness the creative spark as it happens. What they are discovering could have the power to make every one of us more creative.
For most of human history, our brains dealt with pretty straight forward problems. But that brain is the exact same one we now use to post pictures of our pets on social media, fill out Excel spreadsheets, and worry about the next payment on our credit card.
