The hierarchy in your brain: Ray Kurzweil at TED2014The hierarchy in your brain: Ray Kurzweil at TED2014

Posted By Thu-Huong Ha

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 […]

The hard problem of consciousness: David Chalmers at TED2014The hard problem of consciousness: David Chalmers at TED2014

Posted By Ben Lillie

“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 […]

The brain is a Swiss Army knife: Nancy Kanwisher at TED2014The brain is a Swiss Army knife: Nancy Kanwisher at TED2014

Posted By Ben Lillie

She 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 suddenly realizing you can’t recognize any of […]

Questions you may have about Mary Lou Jepsen’s TED TalkQuestions you may have about Mary Lou Jepsen’s TED Talk

Posted By Tedstaff

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 […]

A promising first step for those with spinal cord injury: Further reading on electrical stimulation and how it’s helped rats (and one human!) walk againA promising first step for those with spinal cord injury: Further reading on electrical stimulation and how it’s helped rats (and one human!) walk again

Posted By Kate Torgovnick May

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 […]

9 classic movies about memory manipulation, and how they inspired real neuroscience9 classic movies about memory manipulation, and how they inspired real neuroscience

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 […]

4 talks on a strange phenomenon we all experience: consciousness4 talks on a strange phenomenon we all experience: consciousness

Posted By Kate Torgovnick May

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 […]

Lessons from brain soup: Suzana Herculano-Houzel at TEDGlobal 2013Lessons from brain soup: Suzana Herculano-Houzel at TEDGlobal 2013

Posted By Kate Torgovnick May

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 […]

Posted By Karen Eng

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 […]
