   To maybe short-circuit your idea, magneto-encephalography (MEG) uses magnetic field sensors to sense brain activity. Coherent currents from ~100K neurons produce femto-tesla signals (about 1 billionth of the earth's magnetic field). Th

   TMS relies on Faraday's Law - a large transient magnetic field induces electrical currents in the brain. When these currents are large enough, they perturb the activity of neurons nearby. (Neurons communicate based on pulses of dynamic

   We can already make CNT based fibers at scale fairly cheaply. Would happily sell you a shoelace for much less than the $1M that a Nobel prize comes with... http://news.rice.edu/2017/10/16/long-nanotubes-make-s

   This is a critical comment that should be upvoted widely. The reason that this is such a difficult challenge is that the rate of adult hippocampal neurogenesis, even in rodents where everyone believes it happens, is on the order of between

   I'm also only about 1/4 through. Cool to see that the first piece on Neuralink with quotes from significant numbers of the actual team chooses to be long form and in depth.
