    Implanted Brain-Computer Interfaces are getting fast! They're approaching speeds that match unimpaired people typing. But... more electrodes won't be enough to break through the "motor barrier."

    One of my favorite scientific findings: Some languages are very information dense and some less so. Some languages are spoken fast and some slow. And it turns out that people around the world speak at about the same information rate (~39 bps) regardless.

    Replying to @SumnerLN
    It can be tempting to extrapolate the increasing capabilities of electrode-based motor BCIs and claim theyโ€™ll enable superhuman performance in a few years. This paper is one reason to suggest there is a โ€œspeed limitโ€ to consider.

    Human languages encode similar average information rates (~39 bits/s) despite their remarkable differences.

    Our work made the cover @ScienceTM! In this latest #ultrasound๐Ÿซฑ๐Ÿฝโ€๐Ÿซฒ๐Ÿป#neurotech work, we demonstrate functional ultrasound imaging (fUSI) of human brain activity through an acoustically transparent cranial window, opening new doors for non-invasive, high-resolution neuroimaging. ๐Ÿงต

    New Ultrasound BCI results are out! "I remember how impressive it was when this kind of predictive decoding worked with electrodes two decades ago, and it's amazing now to see it work with a much less invasive method like ultrasound," -@mikhailshapiro .

    "China's brain-computer interface technology is catching up to the US. But it envisions a very different use case: cognitive enhancement." Interesting perspective from @emilylmullin in @WIRED
