Science made this paralysed monkey able to walk!

Science has no limits, we know that and with the latest major advancements in the technological and biological fields are capable of anything. Here we are talking about how science made a paralysed monkey walk again? Might you be thinking a paralysed monkey walking? how?

With some biometrics and electricity, the clever scientists made this possible.

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. 

Study coauthor David Borton, a near engineer at Brown University, says he was surprised by how effortlessly the animals took to the technology. “Their behaviour did not make us think that they were bothered by it at all,”

“They didn’t turn around and look at their legs—they just walked.”

Brain implant sends wireless signals to electrodes implanted in the monkeys’ lumbar spines, which then stimulate the spinal cord. The 96-electrode array, implanted in the part of the motor cortex that controls the back legs, sent out 40 MB of data per second.

What else is needed when a poor paralysed monkey is able to walk with the help of science. Is this the indication that the in future human bodies will be controlled through wireless communication?
