Worldwide, scientists are engaged in an effort to transfer the human brain to an avatar. Their goal is to transform humans into digital beings and thereby free them from the curse of aging, and from death. So do we really need a body? Can we become immortal?
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.
What is memory? How do our memories change from childhood to adulthood? How we can build up greater brain reserves to power our mind into old age? Brain epigenetics, how the expression of our DNA can be changed by our experiences, is an intriguing new area of science with huge health implications.
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.
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.
