Roses are red, violets are blue but according to the latest understanding these colours are really an illusion. One that you create yourself. Horizon reveals a surprising truth about how we all see the world. You may think a rose is red, the sky is blue and the grass is green, but it now seems that the colours you see may not always be the same as the colours I see. Your age, sex and even mood can affect how you experience colours. Scientists have unlocked the hidden power that colours can have over your life - how red can make you a winner, how blue makes time speed up, and more.
Consciousness is perhaps the biggest riddle in nature. In the first part of this three part video series, we explore the origins of consciousness and take a closer look on how unaware things became aware.
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?
At 38 years old, Susan Polgar has reached heights that few women have ever equalled in the chess world. Despite the common assumption that men’s brains are better at understanding spatial relationships, giving them an advantage in games such as chess, Susan went on to become the world’s first grandmaster. Susan’s remarkable abilities have earned her the label of ‘genius’, but her psychologist father, Laszlo Polgar, believed that genius was “not born, but made”. Noting that even Mozart received tutelage from his father at a very early age, Polgar set about teaching chess to the five-year-old Susan after she happened upon a chess set in their home. “My father believed that the potential of children was not used optimally,” says Susan.
In the 1940s Dr. Walter Freeman gained fame for perfecting the lobotomy, then hailed as a miracle cure for the severely mentally ill. It was hailed by the New York Times as "surgery of the soul," a groundbreaking medical procedure that promised hope to the most distressed mentally ill patients and their families. But what began as an operation of last resort was soon being performed at some fifty state asylums, often to devastating results. Little more than a decade after his rise to fame, Walter Freeman, the neurologist who championed the procedure, was decried as a moral monster, and lobotomy one of the most barbaric mistakes of modern medicine. American Experience presents The Lobotomist, the gripping and tragic story of an ambitious doctor, the desperate families who sought his help, and the medical establishment that embraced him. From award-winning producers Barak Goodman and John Maggio (The Boy in the Bubble, The Fight), this one-hour film features interviews with Dr. Freeman's former patients and their families, his students, and medical historians, and offers an unprecedented look at one of the darkest chapters in psychiatric history.
The latest discoveries in neuroscience present a new view of how the brain ages. Overturning decades of dogma, scientists recently discovered that even into our seventies, our brains continue producing new neurons. Scientists no longer hold the longstanding belief that we lose vast numbers of brain cells as we grow older. The normal aging process leaves most mental functions intact, and may even provide the brain with unique advantages that form the basis for wisdom. The aging brain is also far more resilient than was previously believed.
In this episode I visit a researcher who is studying memory by using machine learning and neuroimaging to detect and predict people's brain states. I also travel to Japan to meet with a team working on ways to record the content of peoples’ dreams.
