Australian researchers have created a “bionic spinal cord.” They claim that this device could give paralyzed people significant hope of walking again. And if that’s not enough, it could do it utilizing the power of thought and without the necessity of open brain surgery.
A research team from the Vascular Bionics Laboratory at the University of Melbourne developed the novel neural-recording device, which both eschews invasive surgery and decreases the risks of a blood-brain barrier breach by being implanted into the brain’s blood vessels.
Developed under DARPA’s Reliable Neural-Interface Technology (RE-NET) program, the Stentrode can potentially safely expand the use of brain-machine interfaces (BMIs) in the treatment of physical disabilities and neurological disorders.
The researchers describe their “proof-of-concept results” which come from a study conducted on sheep, demonstrating high-fidelity measurements taken from the region of the brain responsible for controlling voluntary movement (called the motor cortex) with the use of the novel device which, as it happens, is just about the size of a paperclip.
Notably, the device records neural activity that has been shown in pre-clinical trials to move limbs through an exoskeleton.
The team, led by neurologist Thomas Oxley, M.D., published their study in an article in the journal Nature Biotechnology.
