Come work with me! 🥳
Sergey Stavisky@SergeyStavisky12 Aug 2025
We're hiring a Clinical Neurotechnology Research Assistant (CNRA)! Application link in next post. We'll start reviewing applicants after August 25th Please RT 🔁
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.

So exciting that this is up! Incredible work @NS_Card Great thread explaining it all 📖👇

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👇

New brain-computer interface preprint led by PhD student Tyler Singer-Clark! This video of a man with paralysis accurately controlling a cursor looks like something you've seen since ~2017. BUT! This is driven by multielectrode arrays in ventral (speech) motor cortex‼️ 1/

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
Top panel: schematic showing a BCI participant with 4 arrays in speech motor cortex. He is seeing his attempted speech decoded as text on screen and perceives a mistake (How are you --> "how were_"). Bottom panel: Three example electrodes' firing rates aligned to time since feedback. There is an increase in firing rates starting ~200 ms after the word is shown, with large differences on these electrodes between feedback to correct vs incorrect words.

Thanks @ConversationUS for inviting me to write an article about how our brain-to-text decoder works! Check it out: theconversation.com/from-tho…

From thoughts to words: How AI deciphers neural signals to help a man with ALS speak

Listening in on neural activity is a promising way of restoring the ability to communicate for people whose bodies no longer can. Artificial neural networks are the key middleman in the process.

This podcast points out some of the difficulties faced by people living with ALS. It also highlights how a person living with paralysis can use a BCI to communicate with friends, family, and care partners. The impact of disease on care-partners is often under-appreciated!
