Regeneration: The speakers in Session 7 at TEDGlobal 2013Session 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 […]
Lessons from brain soup: Suzana Herculano-Houzel at TEDGlobal 2013For 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 […]
Introducing the RoboRoach: Greg Gage at TEDGlobal 2013Talking 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 […]
Why your brain doesn’t want you to lose weight: Sandra Aamodt at TEDGlobal 2013Standing on the TED stage looking stunning in a blue dress, neuroscientist and author Sandra Aamodt reveals that three and a half years ago on New Year’s Eve, she made a decision: She gave worrying about her weight. Instead, she learned to eat mindfully — and lost 10 pounds. For Aamodt, who had been dieting […]
The neuroscience of sleep: Russell Foster at TEDGlobal 2013Neuroscientist Russell Foster opens a session of TEDGlobal all about … us, asking the question: Why do we sleep? Thirty-six percent of our lives are spent asleep, which means, if you live to 90, you’ll have slept for 32 years. But we don’t appreciate sleep enough, says Foster. He quotes Thomas Edison — “Sleep is […]
Thomas Insel’s insights on mental health: a tale of two TED playlistsIn the past 30 years, major advances have been made when it comes to treating several serious diseases. Today, there are 85% fewer deaths from leukemia and 63% fewer fatalities from heart disease than there were then. Meanwhile, while AIDS was once considered a death sentence, people with the disease can now live to old […]
Further readings in game theory: How it applies to marriage, kidney donation chains and government gridlockHow do we negotiate when to sell a stock, whether to rat out a partner in crime, how to play a poker hand, or what to ask for when negotiating a job offer? In each of these situations, the actions of others will greatly affect our outcomes — and yet, we have no idea what […]
7 talks about fruit flies“Raise your hand if you think that basic research on fruit flies has anything to do with understanding mental illness in humans,” David Anderson begins today’s talk, given at TEDxCaltech. While few hands shoot in the air, Anderson goes on to explain the connection — that research conducted by manipulating brain chemicals in fruit flies […]
Training the brains of psychopaths: Daniel Reisel at TED2013Daniel Reisel is here to talk about our brains. In particular, how we might change them–and how this kind of thinking might just change the tenor of society as a whole. He introduces us to Joe, who’s 32, and a murderer. Reisel met Joe in Wormwood Scrubs, a high-security prison that houses England’s most […]
7 talks on mapping the human brainIn his State of the Union address, US President Barack Obama teased the importance of mapping the human brain, hinting that it could be a good investment in the future. According to The New York Times, the president will soon announce a decade-long plan to support the comprehensive rendering of the brain as part of […]
7 talks on monkeys, and 7 talks on mind controlMiguel Nicolelis begins today’s talk by showing you what a brainstorm looks and sounds like. “This is 100 brain cells firing,” says Nicolelis. “Everything that defines what human nature is comes from these storms that roll over the hills and valleys of our brains and define our memories, our beliefs, our feelings, our plans for […]
TED Weekends wonders: Can you reset your brain?One morning when she woke up, Jill Bolte Taylor felt pain behind her left eye similar to what she’d felt biting into an ice cream cone. Soon, her own appearance — from her hands to her reflection — felt utterly bizarre to her. Next she lost her balance and then her internal chatter simply stopped […]
Spotting neuro-fiction: A guide to dissecting overblown neuroscience headlinesNeuroscientist Molly Crockett has a secret to share: if you want to make better decisions, eat a grilled cheese sandwich. In today’s talk, filmed at the TEDSalon in London, Crockett shares how she accidentally had a part in circulating this message. Several years ago, Crockett and her fellow researchers set out to study how serotonin […]
On nature versus nature: A neuroscientist knee-deep in diapers reflectsBy Daniel Colón-Ramos I could not have designed a better experiment if I had tried. I am a neuroscientist and I am the father of two-year old triplets—two identical and one fraternal. As a professor at Yale University, I spend most of my time designing experiments, researching or teaching about the brain and the nervous […]
Play with the brain: An online game that’s helping map the connections of the retinaSebastian Seung is one of the most influential explorers of our time — and his terrain is the human brain. You may remember Seung’s talk from TEDGlobal 2010, in which he uses the relatively new term “connectome,” to describe the connections between each of the hundreds of millions of neurons in our brains that make […]
