A paralyzed Ohio man was able to feed himself for the first time in eight years, after doctors implanted sensors in his brain that sent signals to his arm. (March 29)
Dr Jordan Nguyen has designed technology that allows Jess Irwin to play music with her eyes.
A clinical research publication led by Stanford University investigators has demonstrated that a brain-to-computer hookup can enable people with paralysis to type via direct brain control at the highest speeds and accuracy levels reported to date.
Typing with your mind. You are paralyzed. But now, tiny electrodes have been surgically implanted in your brain to record signals from your motor cortex, the brain region controlling muscle movement. As you think of mousing over to a letter (or clicking to choose it), those electrical brain signals are transmitted via a cable to a computer (replacing your spinal cord and muscles). There, advanced algorithms decode the complex electrical brain signals, converting them instantly into screen actions.

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.

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.
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.
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.
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.
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.
