🔘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

🔘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

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?"
