I'm impressed they get that much accuracy from the motor cortex. I posted this[1] before - I imagine detecting signals at the spinal cord would provide even greater accuracy (not necessarily in this case). I'm really excited either way.
I'd like to know more about the implanted array though. My impression was that all arrays induce scarring and lose effectiveness over time.
Also, isn't paralysis in ALS caused by the death of motor neurons? If that's so, what exactly was the array sampling? Is it just that there's too few neurons to control muscles, but still enough to type?

- poizan42 10y ago> A motor neuron (or motoneuron) is a nerve cell (neuron) whose cell body is located in the spinal cord and whose fiber (axon) projects outside the spinal cord to directly or indirectly control effector organs, mainly muscles and glands. The neurons in the motor cortex are not motor neurons.
- oregontechninja 10y agoThat was my question as well, can anybody provide an answer? Will they need to clear out the scar tissue periodically? Also, I'm unsure, but this might help prevent scarring and provide a closer to natural interface. http://www.sciencealert.com/scientists-build-an-artificial-neuron-that-fully-mimics-a-human-brain-cell http://www.sciencealert.com/scientists-build-an-artificial-n... I like to keep tabs on this stuff, and would like one day to have an interfaced helper like Siri (Open source alternative of course) that I could use to help my memory.
