🔘Speech motor cortex enables BCI cursor control and click
tl;dr: demonstrated that ventral motor cortex (typically used for speech) can enable high-performance cursor control • rapid calibration (40 seconds) and accurate control (2.90 bits/sec) from vPCG neural signals • all 4 arrays showed click-related activity, with best cursor control from dorsal 6v area • system enabled real-world computer use including Netflix browsing and gaming link:https://doi.org/10.1101/2024.11.12.623096
🔘Optogenetic stimulation of a cortical biohybrid implant guides goal directed behavior
tl;dr: novel BCI approach using living neurons on brain surface instead of invasive electrodes • achieves 50% neuron survival by avoiding vascular damage during implantation • transplanted neurons naturally integrate and show spontaneous activity • mice successfully detect optogenetic stimulation to perform reward task link: https://www.biorxiv.org/content/10.1101/2024.11.22.624907v1 press:https://science.xyz/technologies/biohybrid/
my thought: speech motor cortex enabling netflix browsing in 40 seconds of calibration? that's the kind of real-world usability we've been waiting for. not just lab demos, but actual everyday control.
the biohybrid approach is tackling the integration problem from a completely different angle. getting living neurons to interface with the brain might sound complex, but it could be the elegant solution we need.
Pretty exciting to see BCI tech moving from "can we do it?" to "how do we make it better?"

One thing that Telegram now offers to all users is the ability to “disappear” messages or set remote deletion deadlines. That enables users to have much more control over how long people can access what you’re sending them. Given that Russian law enforcement officials are reportedly (via Insider) stopping people in the street and demanding to read their text messages, this could be vital to protect individuals from reprisals. Telegram users are able to send files of any type up to 2GB each and access them from any device, with no limit on cloud storage, which has made downloading files more popular on the platform. Either way, Durov says that he withdrew his resignation but that he was ousted from his company anyway. Subsequently, control of the company was reportedly handed to oligarchs Alisher Usmanov and Igor Sechin, both allegedly close associates of Russian leader Vladimir Putin. He adds: "Telegram has become my primary news source." That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future.
