We may, as Joan Didion once wrote, tell ourselves stories in order to live—but Uri Hasson is looking for a few more reasons. The neuroscientist based at Princeton University researches the neurological basis of human communication and storytelling, and in session 11 at TED2016, he shows off some surprising findings. Functional magnetic resonance imaging (fMRI) […]
Greg Gage is a reliable source of both shock and awe at TED. Onstage over the years, this TED Fellow has demonstrated his low-cost DIY teaching kits by amputating a cockroach leg to show how neurons fire, remote-controlling a cyborg cockroach to demonstrate how electrical stimulation guides behavior, and taking away an audience member’s free will to show how one person’s brain can control the arm movements of […]
This summer, the country that perfected soccer proved it’s just as formidable a foe off the pitch as it is on. On the first day of the 2014 World Cup, 29-year-old Juliano Pinto, paralyzed from his chest to his toes, did the seemingly impossible: He gave the opening kick just by thinking. Eighteen months earlier, Brazilian […]
Ray Kurzweil returns to the TED stage to explain his new (kind of old) theory of the mind. He first wrote his theory as a paper 50 years ago, but today there’s a plethora of new evidence to support it. First, a refresher on the story of the neocortex, which means “new rind.” Two hundred […]
“Right now you have a movie playing inside your head,” says philosopher David Chalmers. It’s an amazing movie, with 3D, smell, taste, touch, a sense of body, pain, hunger, emotions, memories, and a constant voice-over narrative. “At the heart of this movie is you, experiencing this, directly. This movie is your stream of consciousness, experience […]
Watch this talk on TED.com Onstage at TED, Nancy Kanwisher starts by telling us one of the most surprising results from recent neuroscience discoveries: The brain is not a general-purpose processor, but a collection of specialized components, “collectively building up who we are as human beings and thinkers.” Imagine, she says, walking into a daycare center and […]
Mary Lou Jepsen’s talk about the future of brain-reading devices was widely discussed at TED2013 and, after the conference, we received a few very specific technical and scientific questions from attendees who watched it live. Jepsen’s is the kind of talk that tests the limit of TED’s short-talk format — it’s full of technical information […]
Ed Boyden is the head of the Synthetic Neurobiology group at the MIT Media Lab, where he works on tools to map, control, record — and maybe even someday build — the brain. Boyden has worked on optogenetics, a technique which deploys light-sensitive molecules to the brain and then applies light to them to “turn […]
Grégoire Courtine and the scientists in his lab helped a paralyzed rat learn to walk again, voluntarily, through a treatment that combined drugs, electrical stimulation of the lower spinal cord, the support of a robotic arm and a little bit of chocolate. When their study appeared in the June 2012 issue of Science, it sparked […]
Total Recall, Eternal Sunshine of the Spotless Mind, Inception. In today’s talk, MIT neuroscientists Steve Ramirez and Xu Liu admit that their latest study — in which they located a specific memory in a mouse’s brain and designed a system to activate and deactivate it at will — might remind people of these movies. And there […]
We spend about a third of our lives asleep — a figure that may make all that time spent in bed seem like a waste. But according to neuroscientist Russell Foster, it is quite the opposite. In today’s talk, given at TEDGlobal 2013, Foster explores why we sleep, a question which no one has been […]
John Searle studies consciousness — which, as he points out in today’s talk, is a “curiously neglected subject in our scientific and philosophical culture.” Curiously — because it is, after all, a pre-condition for anything else we think about. And yet neglected — because consciousness is a subject that makes scientists huffy (they see it […]
Biologist, poet and fledgling entrepreneur Ivana Gadjanski has worked on using animal toxins as a possible treatment for MS, and is growing bones and cartilage in dishes. She has also published two books of poetry in Serbia. Now she’s developing Pubsonic, an online research tool that allows users to access free medical journal papers via […]
Session 7, “Regeneration,” couldn’t come at a better time; it’s the end of the second day of TEDGlobal 2013, and we could all use a little repair and restoration. In this session, four scientists and researchers look closely at the ways in which the body breaks down — and how we can rebuild them. Here […]
For decades, scientists said that the human brain contains 100 billion neurons. However, when neuroscientist Suzana Herculano-Houzel hunted for the source of this often-quoted number, she couldn’t locate one. So she set out to count herself … by making brain soup. She brings a vial of brain soup with her onto the TEDGlobal 2013 stage. This […]
Talking as fast and fervently as a circus busker, TED Fellow Greg Gage introduces the world to RoboRoach — a kit that allows you create a cockroach cyborg and control its movements via an iPhone app and “the world’s first commercially available cyborg in the history of mankind.” “I’m a neuroscientist,” says Gage, “and that […]
