A spinal cord injury can sever the communication between your brain and your body, leading to paralysis. Fresh from his lab, Grégoire Courtine shows a new method -- combining drugs, electrical stimulation and a robot -- that could re-awaken the neural pathways and help the body learn again to move on its own. See how it works, as a paralyzed rat...

Grégoire Courtine and his interdisciplinary lab imagine new ways to recover after devastating, mobility-impairing injury to the spinal cord.

Aspiring Olympic skier Janine Shepherd was nearly killed when she was hit by a truck during a training bike ride. Paralysed and immobile for six months, she was given a grim picture for recovery. But not only did she teach herself to walk again— she learned to fly.

Grégoire Courtine is the head of the Center for Neuroprosthetics and Brain Mind Institute of the Life Science School at the Swiss Federal Institute of Technology Lausanne (EPFL). He starts his TED Talk with a story of a mentor of his, the late Christopher Reeve, who spent the last years of his life in a wheelchair after a paralyzing spinal c...

About this event: At the 2nd annual TEDxBoston event we brought together storied professors, inspiring entrepreneurs, forward thinkers, radical architects, intriguing designers, brilliant scientists and astounding performers who make the greater Boston area one of the most exciting and promising cities in which to launch a business or a social enterprise. We h...

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 a lot of excitem...

The second day of mainstage talks at TEDGlobal 2013 offered four densely packed sessions full of the possibility for natural, geopolitical, social and artistic change, both improvised and well-considered -- and more than one magic moment. Here are just a few of the best. Brain soup. Suzana Herculano-Houzel figured out how to count the num...

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 neuroscientist M...

For Session 4 of TED2020, experts in biohacking, synthetic biology, psychology and beyond explored topics ranging from discovering the relationship between the spinal cord and asparagus to using tools of science to answer critical questions about racial bias. Below, a recap of the night's talks and performances. Andrew Pelling, biomedical...

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 are the speakers who appeared in this se...

About this event: TEDxAmericasFinestCitySalon : Story Time Speakers: Jake Ducey At the young age of nineteen, California surfer, Jake Ducey dropped out of college, left behind a drug filled life and went in search of deeper meaning. His quest led him on a life changing journey that has resulted in his debut book: Into the Wind; My Six-Month Journey Wande...

Dying and death confront every new doctor and nurse. In this book excerpt, Atul Gawande asks: Why are we not trained to cope with mortality? I learned about a lot of things in medical school, but mortality wasn’t one of them. I was given a dry, leathery corpse to dissect in my first term -- but that was solely a way to learn about human anatomy...

Pioneering surgeon Susan Lim performed the first liver transplant in Asia. But a moral concern with transplants (where do donor livers come from ...) led her to look further, and to ask: Could we be transplanting cells, not whole organs? At the INK Conference, she talks through her new research, discovering healing cells in some surprising places.

After decades of research and billions spent in clinical trials, we still have a problem with cancer drug delivery, says biomedical engineer Elizabeth Wayne. Chemotherapy kills cancer -- but it kills the rest of your body, too. Instead of using human design to fight cancer, why not use nature's? In this quick talk, Wayne explains how her lab is ...

You may remember neuroscientist Miguel Nicolelis — he built the brain-controlled exoskeleton that allowed a paralyzed man to kick the first ball of the 2014 World Cup. What’s he working on now? Building ways for two minds (rats and monkeys, for now) to send messages brain to brain. Watch to the end for an experiment that, as he says, will go to ...

When faced with life's toughest circumstances, how should we respond: as an optimist, a realist or something else? In an unforgettable talk, explorer Mark Pollock and human rights lawyer Simone George explore the tension between acceptance and hope in times of grief -- and share the groundbreaking work they're undertaking to cure paralysis.

When you stop comparing yourself to others, you can accomplish great things, says wheelchair athlete Dean Furness. He shares how, after losing the use of his legs in an accident, he discovered a powerful new mindset focused on redefining his "personal average" and getting better little by little.

Everyone experiences pain -- but why do some people react to the same painful stimulus in different ways? And what exactly is pain, anyway? Karen D. Davis walks you through your brain on pain, illuminating why the "pain experience" differs from person to person. [Directed by Brett Underhill, narrated by Addison Anderson].

The average person experiences dozens of individual itches each day. We've all experienced the annoyance of an inconvenient itch — but have you ever pondered why we itch in the first place? Is there actually an evolutionary purpose to the itch, or is it simply there to annoy us? Emma Bryce digs deep into the skin to find out. [Directed by Sashko...

"Bonk" author Mary Roach delves into obscure scientific research, some of it centuries old, to make 10 surprising claims about sexual climax, ranging from the bizarre to the hilarious. (This talk is aimed at adults. Viewer discretion advised.)

Hugh Herr is building the next generation of bionic limbs, robotic prosthetics inspired by nature's own designs. Herr lost both legs in a climbing accident 30 years ago; now, as the head of the MIT Media Lab's Biomechatronics group, he shows his incredible technology in a talk that's both technical and deeply personal — with the help of ballroom...

Anthony Atala's state-of-the-art lab grows human organs -- from muscles to blood vessels to bladders, and more. At TEDMED, he shows footage of his bio-engineers working with some of its sci-fi gizmos, including an oven-like bioreactor (preheat to 98.6 F) and a machine that "prints" human tissue.

Eva Vertes -- only 19 when she gave this talk -- discusses her journey toward studying medicine and her drive to understand the roots of cancer and Alzheimer’s.
