Our new preprint describes a multimodal intracortical brain-computer interface that a man with ALS has used at home, independently, almost every day for >19 months. It decodes both speech and cursor control to enable him to communicate and use his computer. Here’s a quick tour👇

Our new preprint describes an intracortical speech neuroprosthesis that generalizes across users, improving brain-to-text decoding accuracy for existing users by ~2x and enabling high-accuracy decoding for new users with minimal calibration data. biorxiv.org/content/10.64898…

This work demonstrates that pooling intracortical speech data across users is effective for creating robust higher-accuracy speech decoders that generalize to new users with minimal calibration data. Read the preprint for more details: biorxiv.org/content/10.64898…

This was a hugely collaborative project amongst several BrainGate sites and participants! Thanks to all, but especially to my co-first author Zachery Fogg and co-senior authors/mentors @DrDavidBrandman and @SergeyStavisky.

In the research world, Casey Harrell is known by subject name T-15. He’s become a test case, and a point of hope, for people afflicted with ALS to have their voice restored. sfchronicle.com/bayarea/arti…

ALS took his voice. A brain implant helped him speak to his daughter again

Want to work on intracortical speech and language brain-computer interfaces? We're hiring a Clinical Neurotechnology Research Assistant (CNRA)! Application link in next post. We'll start reviewing applicants after April 25th Please RT 🔁
Image with text (copied below) and a graphic schematic of a BCI. Neurotech job opportunity UCDavis Neuroprosthetics Lab The Clinical Neurotechnology Research Assistant (CNRA) leads the day-to-day interactions with our clinical trial participants, including going to their home to run brain-computer interface research sessions that our team has put together. For this crucial role we're looking for a highly organized individual with excellent interpersonal skills, who is tech savvy and comfortable learning how to operate our technology with instruction from the PIs and the rest of the research team. The CNRA will be a co-author on resulting publications and is welcome to get further involved in data analysis/experiment design/etc. as long as their core clinical trial responsibilities are met. This role may be of particular interest to someone considering going on to medical school, a PhD program, or a neurotechnology industry role after a couple of years.

I'm really happy to see "brain-to-text" begin crossing over from academia to industry, helping more and more people communicate along the way! And I'm proud that I was able to contribute to this tech during my time at Neuralink.

ALS has gradually taken away Kenneth’s ability to speak. Through Neuralink’s VOICE clinical trial, he’s exploring how a brain-computer interface designed to translate thought to speech could help restore autonomy in his daily life. Watch to learn more:

We will be re-releasing the competition data in a non-normalized continuous format in the coming weeks. We'd also like to re-open the leaderboard so it can serve as a public benchmark for future studies, but have not quite decided how best to do that yet. Stay tuned.
