Can Brain and Spine Implants Help Overcome Paralysis?

Posted November 15, 2016 9:33 AM by Bayes

Let me start with a word of caution regarding this article. The work done is very preliminary, for a very specific type of spinal injury, and far from any sort of human type trial. Still, the work, from an engineering standpoint is interesting so I thought I'd pass along the article:

Brain and Spine Implants Let a Paralyzed Monkey Walk Again

Enabling someone with paralyzed legs to rise to their feet and walk again has long been considered impossible, the kind of bogus miracle promised by faith healers. But who needs faith healers when you have clever scientists and electricity? In the new field of bioelectronic medicine, doctors may soon make the miraculous a reality. A new experiment using paralyzed monkeys has shown the way toward that goal.

Researchers conducted a proof-of-concept study using two monkeys with partial spinal cord injuries, which prevented brain commands from reaching a back leg. The researchers used electrodes implanted in the monkeys’ brains to record electrical signals from the motor cortex, the part of the brain that controls movement. They used a computer to decode those signals and translate them into commands sent to other electrodes implanted in the monkeys’ lumbar spines; those electrodes stimulated the spinal cord. This brain-spine interface (BSI) bypassed the injured part of the spinal cord, allowing the monkeys’ natural movement commands to reach their injured legs.

..."which prevented brain commands from reaching a back leg"...

...as opposed to what? ..a front leg?

Frankensteinian medicine seems to be gaining favor....
