Scientists restore Leg Movement in Primates with Brain-Spinal Interface

Source: kurzweilai.net

An international team of scientists has used a wireless “brain-spinal interface” to bypass spinal cord injuries in a pair of rhesus macaques, restoring nearly normal intentional walking movement to a temporarily paralyzed leg.

The finding could help in developing a similar system to rehabilitate humans who have had spinal cord injuries.

The system uses signals recorded from a pill-sized electrode array implanted in the motor cortex of the brain to trigger coordinated electrical stimulation of nerves in the spine that are responsible for locomotion.

New Body “Communication Highways” with Neuroprostetics

Source: thestar.com

An expert trained at the University of New Brunswick says prosthetics powered by artificial intelligence are no longer the stuff of science fiction — thought-controlled bionic limbs have already arrived and are getting more sophisticated by the day.

Levi Hargrove, director of the Rehabilitation Institute of Chicago and UNB graduate, will return to his alma matter [sic] next week to deliver a lecture on “rewiring humans” who have lost limbs using state-of-the-art artificial prosthetics controlled by the power of the mind.

A brighter Future for wounded Veterans through Brain-Controlled Bionics

Source: science.dodlive.mil

Ever since the first war ever recorded by human beings, paralyzation and amputation of extremities has been a common occurrence. The answer to this problem was usually found in the form of prosthetics or artificial limbs. The oldest documented prosthetic can be traced back to somewhere between 950 and 710 B.C. It was in the form of an artificial toe fashioned from wood and leather. Today, robotic prosthetic limbs are becoming increasingly common, and prosthetics technology continues to advance.

Study: Your Brain can adapt to Dishonesty and Deception

Source: sheppnews.com.au

When it comes to lying, practice makes perfect because the brain slowly adapts to ignore the emotions produced by deception, according to new research.

Whether it’s a ‘‘the dog ate my homework’’ lie or financial fraud, most people know small transgressions can gradually lead to larger ones.

Robot Exoskeleton will help Patients to walk again

Awearable robot exoskeleton is helping paralyzed patients walk again, thanks to a unique new design that promises more fluid movement. Researchers at Beihang University in China and Aalborg University in Denmark, who had their research published on Tuesday in the Review of Scientific Instruments, now have big plans to expand the robot’s capabilities, using brain signals and virtual reality to help make the experience more immersive.

BCI-generated Sensory Feedback from Cortical Stimulation

Source: engineering.com

In the quest to restore movement to people with spinal cord injuries, researchers have focused on getting brain signals to disconnected nerves and muscles that no longer receive messages that would spur them to move.

But grasping a cup or brushing hair or cooking a meal requires other feedback that has been lost in amputees and individuals with paralysis—a sense of touch. The brain needs information from a fingertip or limb or external device to understand how firmly a person is gripping or how much pressure is needed to perform everyday tasks.

Can BCIs convert Thoughts into Text?

Source: sciencedaily.com

Ever wonder what it would be like if a device could decode your thoughts into actual speech or written words? While this might enhance the capabilities of already existing speech interfaces with devices, it could be a potential game-changer for those with speech pathologies, and even more so for “locked-in” patients who lack any speech or motor function.

Brain Implants and Neural Engineering

It would be the ultimate user interface: a device the size of two stacked nickels that allows your thoughts to control computers. The only catch is it’ll have to be implanted in your brain.

That’s what the Department of Defense’s cutting-edge research unit DARPA is working on, as part of President Obama’s BRAIN Initiative, a concerted push to advance neuroscience.

Mind-Controlled Computers: Just a Decade away?

Source: dailymail.co.uk

The first computers cost millions of dollars and were locked inside rooms equipped with special electrical circuits and air conditioning.

The only people who could use them had been trained to write programs in that specific computer’s language.

Today, gesture-based interactions, using multitouch pads and touchscreens, and exploration of virtual 3D spaces allow us to interact with digital devices in ways very similar to how we interact with physical objects.

Paralyzed Man regains Sense of Touch with Brain-Controlled Robot Arm

In the winter of 2004, 28-year-old Nathan Copeland suffered an accident that left him unable to feel any sensation in his arms and fingers. But a decade later, he has now been able to regain his sense of touch through a mind-controlled robotic arm that is directly connected to his brain.
