Neuralink White Paper [2019]
[Elon Musk & Neuralink's "An Integrated Brain-Machine Interface Platform With Thousands Of Channels" inspires this post.] What is Neuralink's primary goal, and what have they done to achieve it? Neuralink's primary goal is to make a high-bandwidth, high-resolution brain computer interface that is also highly scalable and suitable for chronic implantation. While each of the four components of this goal -- bandwidth, resolution, scaling, longevity -- is difficult on its own, Neuralink has made significant progress on each one over the last few years. This post will summarize what Neuralink has achieved in each category, according to their published paper (note: apparently even more has happened than just what they've publicly announced). Bandwidth The very high electrode density in Neuralink's device requires a very high bandwidth transmission interface. Even the USB-C interface (which can carry up to 40Gb/s) discussed in the paper, isn't fast...
