A BCI controlling virtual fingers is used to fly a high-performance virtual quadcopter. BCIs could allow people with paralysis to eventually play multiplayer video games with gamers who use video game controllers. Stanford Neurosurgery Michigan Neurosurgery U-M BME nature.com/articles/s4159…

I’m excited to present our new preprint! An intuitive, bimanual, high-throughput QWERTY touch typing neuroprosthesis for people with tetraplegia. medrxiv.org/content/10.110…

New preprint! We continue our exploration of paralinguistic features in the human brain with “Encoding of speech modes and loudness in ventral precentral gyrus” led by PhD student Aparna Srinivasan 🧵1/5

I wasn't able to make it to BCI Society this year but am very proud of UC Davis Neuroprosthetics Lab postdocs Maitreyee Wairagkar, Nicholas Card, and Liza Okorokova for giving talks+ posters (including Best Poster award to Nick)!

Another preprint 🧵: our first foray into 𝐡𝐲𝐛𝐫𝐢𝐝 𝐜𝐨𝐠𝐧𝐢𝐭𝐢𝐯𝐞 + 𝐦𝐨𝐭𝐨𝐫 𝐬𝐩𝐞𝐞𝐜𝐡 𝐛𝐫𝐚𝐢𝐧-𝐜𝐨𝐦𝐩𝐮𝐭𝐞𝐫 𝐢𝐧𝐭𝐞𝐫𝐟𝐚𝐜𝐞𝐬 Ever wished your phone knew when you perceived an error in the output it gave you (e.g., a transcription typo)? BCIs can! 1/4

In new work led by CS PhD student Xianda Hou, we should a speech BCI that also monitors neural error signals to detect when the users sees (or hears) decoding errors. The key discovery: error-related signals in speech motor cortex neural activity recorded intracortically. 2/4

Using data from the whole recorded neural ensemble, we could decode these errors with reasonable accuracy. Our online proof-of-concept prototype detected 76.5% of decoding errors with a 8.5% false positive rate [I think this can be improved with more electrodes/more data]. 3/4

A man with a severe speech disability is able to speak expressively and sing using a brain implant that translates his neural activity into words almost instantly. go.nature.com/4mXv8yM

Great next-generation speech BCI work led by our very own Maitreyee Wairagkar !

Our researchers UCDavisMedSchool UC Davis Neurological Surgery are not only changing the world, but changing people's lives in real time. World first: brain implant lets man speak with expression ― and sing Sergey Stavisky David Brandman nature.com/articles/d4158…

A new study by Maitreyee Wairagkar shows promise for brain-computer interfaces: A brain-to-voice neuroprosthesis can instantaneously restore intelligible and expressive speech to those with paralysis. nature.com/articles/s4158… Sergey Stavisky David Brandman
