Horizon uncovers the truth about how you really make decisions. Every day you make thousands of decisions, big and small, and behind all them is a powerful battle in your mind, pitting intuition against logic. This conflict affects every aspect of your life - from what you eat to what you believe, and especially to how you spend your money. And it turns out that the intuitive part of your mind is a lot more powerful than you may realise.
There are 100 billion individual neurons in the human brain. Working together, they allow us to make sense of, and move through, the world around us. Scientists have built replicas of the human brain with computers, but no one has ever successfully made a brain out of humans. On this episode, I’ll travel back to my hometown of Stilwell, Kansas, and turn it into a working brain!
A baby's brain is a mystery whose secrets scientists are just beginning to unravel. The mystery begins in the womb -- only four weeks into gestation the first brain cells, the neurons, are already forming at an astonishing rate: 250,000 every minute.
What happens when your brain is deprived of stimulation? What effect does being cut off from interaction with the outside world have on a person? What effect does it have on me, when I am locked in a windowless, soundproof isolation chamber for three days? In this episode of Mind Field, I take both an objective and a very intimate look at Isolation.
Imagine a world in which you can think but cannot speak. For many stroke survivors, like former football star Junior and landlord Barry, this nightmare is a reality. Inspired by the experience of his brother-in-law, filmmaker Richard Alwyn has made an intensely moving, personal film about language and its loss. Alwyn's brother-in-law, journalist Dennis Barker, had a stroke in 2011 which left him speaking a bizarre, fluent gibberish – just one manifestation of the condition ‘aphasia' in which people lose or have a severely impaired ability to use language. Speechless tells the powerful stories of two men who can no longer take language for granted. Much of the film is made on the Neuro Rehab Unit of the National Hospital for Neurology and Neurosurgery in London's Queen Square. There, Alwyn meets 55 year old Barry who has been in hospital for 4 months since a stroke left him barely able to speak. Courageous and determined, Barry's personality constantly triumphs where his language fails. And two years after his stroke when just 35 years-old, former Premier League and international footballer Junior Agogo is still visiting the Unit as he battles to find his way in the world with depleted language. “I had thoughts but I'm saying, where was my voice? I was baffled, man.” Speechless raises questions that straddle philosophy and science. Can we understand the world if we don't have language to name and describe it? Can we think without language? How much is our identity wrapped up in language? These questions are at the heart of conversations that Alwyn has with clinicians and therapists working to get Barry and Junior back into the world. Speechless is fascinating and moving, upsetting and uplifting in its depiction of the isolating and estranging condition, aphasia.

Professor Shapiro reaches back into history to show that artists, architects and mathematicians have also employed visual “tricks” to baffle and entertain us by manipulating perspective and challenging our ideas of what is real and what is fake.
