A new study published Thursday in Cell Stem Cell is set to further stoke the debate over whether our brain can actually grow back neurons as we age. The research found that people, even into their golden years, are regenerating their stock of neurons right up until the point of death—seemingly contradicting the…
A popular theory about how the human brain works—one that’s inspired both neuroscience research and sketchy health fads alike—is just plain wrong, suggests a new study published Thursday in Nature. The adult brain might not be able to naturally restock its supply of neurons after all.
Recall The Matrix. Neo asks Trinity if she can fly a helicopter. She can’t. This has happened to most of us. But then, she makes a phone call to Tank, who uploads the knowledge of helicopter flight directly into her brain.
Birds are capable of extraordinary behavioral feats, from solving complex puzzles to tool making. There may be good reason for that. A new study shows that, pound for pound, birds pack more neurons into their small brains than mammals, including primates.
This recording lets us see 77 of the nematode’s 302 neurons light up like a Christmas display as the worm freely wriggles around on a plate. This is amazing. We’re watching an animal’s mind at work.
The brain is a very complicated chunk of stuff, with billions of individually simple neurons combining to give rise to very complex behavior. This interactive video does a wonderful job of describing how it all works.
By directing pulses of light onto specific regions of the brain, researchers from Columbia University Medical Center induced feelings of extreme thirst in perfectly well hydrated mice — causing them to drink the equivalent of seven pints of water for a human.
These are probably the most detailed images of nerves that have ever been produced. Italian researchers have developed a new technique for labelling nerves in living mice, which includes an artificial tagging system. The increased resolution is allowing scientists to see things they couldn't before, including nerves…
Whatever you happen to call them—crawfish, crawdads, mudbugs—crayfish are pretty tasty. They also have a pretty remarkable ability to regenerate neurons from blood cells. Understanding brain regeneration in these little crustaceans might one day help us understand how it could work in humans.
Cognitive computing has been one of our most exciting frontiers for years. It's enticing to think that we can someday build a computer that's as powerful and as efficient as a brain. IBM's latest miracle chip just got us closer than ever.
From microscopic coral to massive planets, the natural world is full of beauty on a scale that can only be seen with the aid of a microscopic or a telescope. Announced today, the winners of the 11th annual International Science and Engineering Visualization Challenge—sponsored by the journal Science and the U.S. …
Neuroscientists have learned that dendrites do more than just provide passive wiring in the brain. These nerve cell connectors also process information, essentially functioning as tiny computers. Our brains, it would appear, pack more computing power than we assumed.
After receiving his Phd in neuroscience at University of Pennsylvania, Greg Dunn decided to explore the structures of the brain and the rest of the nervous system through the medium of paint. Informed by Japanese sumi-e ink wash painting, Dunn paints meditative scenes of neurons the way many artists have painted…
The problem with cells is that they have an expiry date. They can only replicate so many times before they hit a biologically predetermined limit and sputter out. But a recent study by neuroscientist Lorenzo Magrassi from the University of Pavia in Italy shows that mammalian neurons are not subject to this kind of…
In the future, when doctors read your mind they won't see repressed scenes from your childhood—they'll see neurons exploding like chains of firecrackers.
Scientists just captured the most detailed footage of a single neuron in action ever. In the timelapse video above you can even see individual proteins moving through different pathways within the cell. This is what your feelings look like.
Creating a wiring diagram of the human brain's neurons is an oft-discussed idea that remains in the realms of science fiction. Scale that problem down to tackling a mouse brain, however, and you're in the realms of what science can just about manage—with your help.
That favorite childhood memory of yours—you know, the one that still seems like just yesterday, the one that you can still smell and taste—may actually be the result of a select few neurons firing deep within your brain.
What is it that makes the human brain so special? Sure it's big — but it's far from the biggest brain around. You've heard that your brain contains 100 billion neurons — but where does that number really come from, and how does it stack up against other species?
When it comes time for honeybee swarm to split off from their mother colony and find a new place to live, something remarkable happens. To communicate most effectively, they organize themselves exactly like the neurons of a complex brain.
