In fact, it is said that the probe array is so small, it is capable of floating along inside a person’s brain. The whole idea of this probe array is to assist amputees and people who have spinal cord injuries, helping them control artificial limbs.
The neural array would build a “bridge”between the brain and artificial limbs, so that someone who happens to be injured in the spine and told in the past that he or she would never be able to walk again, would be able to defy all odds. Of course, this is not a risk-free neural implant, as there are risks involved during “installation”, but it is as safe as it gets since the probe array would be implanted in the brain’s subarachnoid space, allowing it to remain within the brain’s protective membranes. Future design tweaks are required to make the probes fully implantable.
