🔘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?"

The company maintains that it cannot act against individual or group chats, which are “private amongst their participants,” but it will respond to requests in relation to sticker sets, channels and bots which are publicly available. During the invasion of Ukraine, Pavel Durov has wrestled with this issue a lot more prominently than he has before. Channels like Donbass Insider and Bellum Acta, as reported by Foreign Policy, started pumping out pro-Russian propaganda as the invasion began. So much so that the Ukrainian National Security and Defense Council issued a statement labeling which accounts are Russian-backed. Ukrainian officials, in potential violation of the Geneva Convention, have shared imagery of dead and captured Russian soldiers on the platform. As the war in Ukraine rages, the messaging app Telegram has emerged as the go-to place for unfiltered live war updates for both Ukrainian refugees and increasingly isolated Russians alike. As such, the SC would like to remind investors to always exercise caution when evaluating investment opportunities, especially those promising unrealistically high returns with little or no risk. Investors should also never deposit money into someone’s personal bank account if instructed. "Like the bombing of the maternity ward in Mariupol," he said, "Even before it hits the news, you see the videos on the Telegram channels." Given the pro-privacy stance of the platform, it’s taken as a given that it’ll be used for a number of reasons, not all of them good. And Telegram has been attached to a fair few scandals related to terrorism, sexual exploitation and crime. Back in 2015, Vox described Telegram as “ISIS’ app of choice,” saying that the platform’s real use is the ability to use channels to distribute material to large groups at once. Telegram has acted to remove public channels affiliated with terrorism, but Pavel Durov reiterated that he had no business snooping on private conversations.
