Crayfish Can Turn Ordinary Blood Cells Into Neurons

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.


This Weird Rainbow Nipple Is Actually A Sophisticated Model Of A Brain

There are a lot of things I can think of when I see this gelatinous rainbow mass, but I do not think “brain.” Yet this funny-looking thing is one of the most complex models scientists have ever developed to study what traumatic injury does to brain cells.


Extreme Close Up Photo Of A Living Human Brain

Photo: A living human brain. Looks gross. But think about how amazing this is. You have one of these things inside your head, a mass of organic matter in which billions of connections make you — every memory, everything that ever was in your life is inside this mass. So yes, it may look gross, but it’s freaking amazing.


IBM's New Brain-Like Chip Squeezes One Million Neurons Onto A Stamp

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.


This Is Why We Have Brains In Our Heads And Not Our Bums

Video: This video explains why our brains are at the end of our bodies in our heads. Evolutionary advantage led to sensory organs clustered together around animals’ eating ends and early brains developed. Only later did animals start to protect these assets with skulls and then develop other advantages such as jaws.


Scientists Have Located The Brain's On/Off Switch For Consciousness

Every one of us loses consciousness on a daily basis: it’s called sleep. But scientists have never understood which part of the brain controls when you’re conscious and when you’re not. Now, researchers seem to have found it by coincidence while studying an epileptic patient — and used electronic brain stimulation to flip the switch on and off.


What The Synapses In Your Brain Actually Look Like

Without synapses, your neurons wouldn’t be able to communicate and your brain would be little more than a ball of meat. Exactly what synapses look like has been a mystery until now, and it turns out that even though their job is simple, they’re complicated as hell.


Scientists Cured Paralysis In Mice With Stem Cells And Lasers

This is wild. Chasing the elusive dream of curing paralysis, a team of scientists used stem cells and optogenetics to circumvent the central motor system of lab mice whose nerves had been cut. This enabled them to blast individual motor neurons with a laser, triggering movement in the legs of the mice.


Looking At Orange Light Is Like Drinking A Cup Of Coffee

Light is an incredibly powerful force. Sure, it helps us see and gives us fast internet, but medical researchers keep stumbling upon new positive side effects. A team of Belgian scientists, for instance, just discovered how a 10-minute blast of orange light increases brain activity related to cognition and alertness.


Scientists Unlock Mystery Of Out-Of-Body Experiences

Some people claim that they have experienced out-of-body experiences — aka “astral trips” — floating outside of their bodies and watching themselves from the outside. A team of scientists found someone who says she can do this at will and put her into a brain scanner. What they discovered was surprisingly strange.
