Stories for "neuroscience"

What happens in the brain when we hear stories? Uri Hasson at TED2016

What happens in the brain when we hear stories? Uri Hasson at TED2016

on

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) []

The neuro-revolution is coming: Greg Gage’s neuroscience kits put research in the hands of the curious

The neuro-revolution is coming: Greg Gage’s neuroscience kits put research in the hands of the curious

on

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 []

The hierarchy in your brain: Ray Kurzweil at TED2014

The hierarchy in your brain: Ray Kurzweil at TED2014

on

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 TED2014

The hard problem of consciousness: David Chalmers at TED2014

on

“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 TED2014

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

on

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 []

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

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

on

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 []

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 again

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 again

on

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 []

4 talks on a strange phenomenon we all experience: consciousness

4 talks on a strange phenomenon we all experience: consciousness

on

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 []

Regeneration: The speakers in Session 7 at TEDGlobal 2013

Regeneration: The speakers in Session 7 at TEDGlobal 2013

on

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 []

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 []
