Researchers at the University of Massachusetts Medical School are the first to show that it’s possible to reverse the behavior of an animal by flipping a switch in neuronal communication. The research, published in PLOS Biology, provides a new approach for studying the neural circuits that govern behavior and has important implications for how scientists think about neural connectomes.

New technologies have fueled the quest to map all the neural connections in the brain to understand how these networks processes information and control behavior. The human brain consists of 10¹¹ neurons that make 10¹⁵ connections. The total length of neuronal processes in the human brain is approximately 4 million miles long, similar in length to the total number of roads in the U.S. Along these networks neurons communicate with each other through excitatory and inhibitory synapses that turn neurons on or off.

The neuronal roadmap, or connectome, however, doesn’t include information about the activity of neurons or the signals they transmit. How stable are these neural circuits in the brain? Does their wiring constrain the flow of information or the behaviors they control? The complexity of the human brain makes it almost impossible to address these questions.

Cancer claimed Kim Suozzi at age 23, but she chose to have her brain preserved with the dream that neuroscience might one day revive her mind.

The US government said today (Sept. 11) that it’s successfully made a Luke Skywalker-like prosthetic arm that allows the wearer to actually feel things.

At a conference in July, the US Defense Advanced Research Projects Agency (DARPA) presented the achievements it’d had to date in building a robot arm that can be controlled by a human brain. A little over two months later, the agency has announced at another conference that it’s managed to update the technology to give the wearer the feeling of actually being able to sense things with the arm.

So, you think you’ve seen it all? You haven’t seen anything yet. By the year 2030, advancements will excel anything we’ve seen before concerning human intelligence. In fact, predictions offer glimpses of something truly amazing – the development of a human hybrid, a mind that thinks in artificial intelligence.

Ray Kurzweil, director of engineering at Google, spoke openly about this idea at the Exponential Finance Conference in New York. He predicts that humans will have hybrid brains able to connect to the cloud, just as with computers. In this cloud, there will be thousands of computers which will update human intelligence. The larger the cloud, the more complicated the thinking. This will all be connected using DNA strands called Nanobots. Sounds like a Sci-Fi movie, doesn’t it?

Kurzweil says:

Synthetics startup Ras Labs is working with the International Space Station to test “smart materials” that contract like living tissue. These “electroactive” materials can expand, contract and conform to our limbs just like human muscles when a current moves through them – and they could be used to make robots move and feel more human to the touch.

Ras Labs co-founder Lenore Rasmussen accidentally stumbled upon the synthetic muscle material years ago while mixing chemicals in the lab at Virginia Tech. The experiment turned out to be with the wrong amount of ingredients, but it produced a blob of wobbly jelly that Rasmussen noticed contracted and expanded like muscles when she applied an electrical current.

It would be years later when Rasmussen’s cousin nearly lost his foot in a farming accident that she would start to employ that discovery to robotic limbs and space travel. The co-founder thought her cousin might lose his foot and started researching prosthetics.

Italian doctor Sergio Canavero, along with his Chinese colleague Ren Xiaoping, is set to conduct the world’s first head transplant on a 30-year-old Russian patient suffering from a rare disease. The operation is planned for December 2017.

The project was first announced in 2013, and the man who volunteered for the procedure is Russian Valery Spiridonov, who suffers from the extremely rare, progressive Werdnig-Hoffmann disease.

“Canavero initially joked it would be a Christmas present, but now this is becoming a reality.

Italian neurosurgeon Sergio Canavero grabbed the world’s attention this past winter when he announced his plans to perform the first human head transplant. Many doubted that such an outrageous procedure would ever see the light of day. Now, Canavero has a date on the books.

Thirty-year-old Russian computer scientist Valery Spiridonov is set to become the world’s first head transplant patient in December 2017. Spiridonov suffers from a rare genetic muscle-wasting condition known as Werdnig-Hoffmann disease. There’s currently no known treatment.

As you might not want to imagine, the procedure will be filled with challenges and uncertainties. There’s the hair-raising possibility that the head will reject the body or vice versa. The spinal cord might not fuse properly. Even if everything goes well, there’s no telling whether Spiridonov’s mental capacities or personality will remain the same. He’s embarking on totally uncharted medical territory.

Is there anything 3D printers can’t do? A 54-year-old Spanish man, who had a cancerous tumor in his chest wall, was recently fitted with a 3D printed sternum and rib cage. While the first-of-its-kind implant seems like a Marvel Comics experiment with Adamantium, in reality, it was an ingenious, life saving medical solution that used lightweight yet sturdy, Titanium. The metal printing technique gave the surgeons at the Salamanca University Hospital in Spain the flexibility they needed to customize the complex and unique anatomy of their patient’s chest wall.

They brought in Anatomics, a Melbourne-based company that manufactures surgical products, to help create and print the implant. Based on the patient’s high-resolution CT scan data, the Australian team first created a 3D reconstruction of the patient’s chest wall and tumor so that the surgeons could plan with precision. Next, they used the 3D digital CAD file detailing the patient’s anatomy to build the customized implant, layer by layer, on Arcam’s $1.3 million electron beam metal printer.
