“The results showed that rat cyborgs could be smoothly and successfully navigated by the human mind to complete a navigation task in a complex maze. Our experiments indicated that the cooperation through transmitting multidimensional information between two brains by computer-assisted BBI is promising.”

Brain-machine interfaces (BMIs) provide a promising information channel between the biological brain and external devices and are applied in building brain-to-device control. Prior studies have explored the feasibility of establishing a brain-brain interface (BBI) across various brains via the combination of BMIs. However, using BBI to realize the efficient multidegree control of a living creature, such as a rat, to complete a navigation task in a complex environment has yet to be shown. In this study, we developed a BBI from the human brain to a rat implanted with microelectrodes (i.e., rat cyborg), which integrated electroencephalogram-based motor imagery and brain stimulation to realize human mind control of the rat’s continuous locomotion. Control instructions were transferred from continuous motor imagery decoding results with the proposed control models and were wirelessly sent to the rat cyborg through brain micro-electrical stimulation. The results showed that rat cyborgs could be smoothly and successfully navigated by the human mind to complete a navigation task in a complex maze. Our experiments indicated that the cooperation through transmitting multidimensional information between two brains by computer-assisted BBI is promising.

They are giving a better life to injured animals. 😃

George Will, a political commentator for nearly half a century at The Washington Post, is known to also enjoy weighing in on sports on occasion, most notably baseball. He is fond of repeating the simple but critical observation that these games are a matter of “seconds and inches.”

In digital games, the same maxim applies, but even more so. Fractions of inches matter when targeting the enemy. And critical time is not measured in seconds but in thousandths of seconds.

With that in mind, developers at Canadian startup Brink Bionics have developed a device that promises to boost gamer proficiency by slashing the delay time between an intent to act and execution of the actual action.

“I can feel touching my daughter’s hand or touching my wife’s hand, or picking up a hollow eggshell without crushing it,” Anderson says of his work with Psyonic, a startup operating out of the University of Illinois’ Research Park, in Urbana-Champaign. Psyonic expects to provide commercial prostheses with pressure sensing next year, and ones with sensory feedback sometime after that.

Technology is on the threshold of turning the unthinkable into reality. Awkward, unfeeling prostheses are morphing into mind-controlled extensions of the human body that give their wearers a sense of touch and a greater range of motion.

Along with sensory feedback, Psyonic’s rubber and silicone prosthesis uses machine learning to give its wearers intuitive control. The Modular Prosthetic Limb from Johns Hopkins University promises to deliver “humanlike” strength, thought-controlled dexterity and sensation. It’s currently in the research phase. And Icelandic company Ossur is conducting preclinical trials on mind-controlled leg and foot prostheses. These and other advances could make it dramatically easier for amputees to perform the sorts of tasks most people take for granted.

“It’s all thanks to the sacrifice of the hawk moth Manduca sexta, which is an extremely sensitive smeller, like other moths. When a moth picks up a scent, like that of a flower or a potential mate, the odors bind to proteins inside the antennae, and these proteins in turn activate neurons dedicated to specific chemicals. That means the antennae are producing electrical signals that researchers can tap into. In order to create a sort of moth-drone cyborg, mechanical engineer Melanie Anderson of the University of Washington cold-anesthetized a hawk moth in a freezer before removing its antennae. Then she cut both ends off of a single antenna and attached each to an itty-bitty wire hooked up to an electrical circuit. “A lot like a heart monitor, which measures the electrical voltage that is produced by the heart when it beats, we measure the electrical signal produced by the antenna when it smells odor,” says Anderson, lead author on a recent paper in the journal Bioinspiration and Biomimetics describing the research. “And very similarly, the antenna will produce these spike-shaped pulses in response to patches of odor.””

Researchers slap a living antenna on a drone to give the machine an insanely keen sense of smell. Ladies and gentlemen, meet the “Smellicopter.”

“For example, a number of animals benefit from solar-powered molecules. The pea aphid produces pigments that, with the aid of light, generate adenosine triphosphate, or ATP, the compound that powers reactions with cells. In addition, a stripe of yellow pigment on the exoskeleton of the Oriental hornet (Vespa orientalis) converts light to electricity, which could help to explain why these insects become more active during the middle of the day. Other animals make use of actual photosynthesis, using sunlight, water and carbon dioxide to produce sugars and other vital compounds. Plants and algae rely on chloroplasts, structures within their cells, to carry out photosynthesis, but Elysia sea slugs can steal chloroplasts from algae they graze on, to help them live solely on photosynthesis for months… Many other animals reap benefits from photosynthesis by forming partnerships instead. For instance, most corals partner with photosynthetic symbiotic microbes known as zooxanthellae, while the eggs of spotted salamanders receive valuable oxygen from algae.”

If humans had green skin, for instance, what if it granted us the ability to perform photosynthesis, which plants use to live off of sunlight?

Nearly two years ago, Chmielewski underwent a 10-hour brain surgery at the Johns Hopkins Hospital in Baltimore as part of a clinical trial originally spearheaded by the Defense Advanced Research Projects Agency and leveraging advanced prosthetic limbs developed by the Johns Hopkins Applied Physics Laboratory. Its goal was to allow participants to control [assistive devices](https://medicalxpress.com/tags/assistive+devices/), and enable perception of physical stimuli (touching the limbs) using neurosignals from the brain. Surgeons implanted six electrode arrays into both sides of his brain, and within months he was able to demonstrate, for the first time, simultaneous control of two of the [prosthetic limbs](https://medicalxpress.com/tags/prosthetic+limbs/) through a brain-machine interface developed by APL.

For more than 30 years—following an accident in his teens—Robert “Buz” Chmielewski has been a quadriplegic with minimal movement and feeling in his hands and fingers. But last month he was able to manipulate two prosthetic arms with his brain and feed himself dessert.

A former independent presidential hopeful is vexed at the COVID-19 vaccine at the moment, and for multiple reasons. That would be Zoltan Istvan, a self-described transhumanist candidate who was billed as the “cyborg who is running against President Trump” in press reports throughout 2020. The California hopeful — who ran in the Republican primary — based his campaign on a futuristic message of fusing radical technology with daily life under the motto “Upgrade America.”

Mr. Istvan recently looked into how long it would be before he got a COVID-19 vaccine.

“I took the New York Times’ ‘Find your Place’ in the vaccine line report, and I was near the bottom 15% of the timeline for getting the vaccine — meaning I’ll be nearly last,” Mr. Istvan wrote in an email to Inside the Beltway.
