🔘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?"

Since its launch in 2013, Telegram has grown from a simple messaging app to a broadcast network. Its user base isn’t as vast as WhatsApp’s, and its broadcast platform is a fraction the size of Twitter, but it’s nonetheless showing its use. While Telegram has been embroiled in controversy for much of its life, it has become a vital source of communication during the invasion of Ukraine. But, if all of this is new to you, let us explain, dear friends, what on Earth a Telegram is meant to be, and why you should, or should not, need to care. The regulator said it has been undertaking several campaigns to educate the investors to be vigilant while taking investment decisions based on stock tips. Now safely in France with his spouse and three of his children, Kliuchnikov scrolls through Telegram to learn about the devastation happening in his home country. Multiple pro-Kremlin media figures circulated the post's false claims, including prominent Russian journalist Vladimir Soloviev and the state-controlled Russian outlet RT, according to the DFR Lab's report. For tech stocks, “the main thing is yields,” Essaye said.
