🔘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?"

Ukrainian forces successfully attacked Russian vehicles in the capital city of Kyiv thanks to a public tip made through the encrypted messaging app Telegram, Ukraine's top law-enforcement agency said on Tuesday. WhatsApp, a rival messaging platform, introduced some measures to counter disinformation when Covid-19 was first sweeping the world. 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. At this point, however, Durov had already been working on Telegram with his brother, and further planned a mobile-first social network with an explicit focus on anti-censorship. Later in April, he told TechCrunch that he had left Russia and had “no plans to go back,” saying that the nation was currently “incompatible with internet business at the moment.” He added later that he was looking for a country that matched his libertarian ideals to base his next startup. Oh no. There’s a certain degree of myth-making around what exactly went on, so take everything that follows lightly. Telegram was originally launched as a side project by the Durov brothers, with Nikolai handling the coding and Pavel as CEO, while both were at VK.
