From Brain to Text and Voice: a Rapid-Deploy Neuroprosthesis with Dr Card & Dr Wairagkar
Neurocareers: Doing the Impossible!
Comparison of Utah Arrays and Grid Electrodes for Neural Signal Sampling
This chapter explores the differences in sampling neural signals using penetrating electrodes like Utah arrays versus grid electrodes, comparing precision in targeting single neurons with high resolution to capturing aggregate activity from many neurons with lower resolution. The speakers discuss the advantages, drawbacks, technological advancements, and potential for decoding language from neural signals using different electrode types.
How can we break through the barriers in communication for millions suffering from speech impairments due to ALS, stroke, and other conditions?
Traditional assistive technologies, like eye trackers, are slow and cumbersome, limiting effective communication. However, ongoing research in speech neuroprosthetics shows promising results in restoring seamless communication by decoding speech directly from brain signals.
Enter the groundbreaking work where Dr. Nicholas S. Card and Dr. Maitreyee Wairagkar are bringing change in the development of speech neuroprosthesis. Their award-winning project lead by Dr. David M. Brandman and Dr. Sergey D. Stavisky from UC Davis in collaboration with Stanford, and Brown University teams, introduces a rapidly deployable high-performance speech neuroprosthesis. This innovative technology can convert brain signals into text and voice in real-time, significantly enhancing communication speed and quality for individuals with severe speech impairments.
In this episode, Nick and Maitreyee share their journey of creating a multimodal speech neuroprosthesis and their challenges and remarkable achievements. Learn about their approach to decoding phonemes, integrating large language models, and synthesizing intelligible speech directly from neural activity.
They also delve into their career development journeys, offering valuable advice for those aspiring to follow in their footsteps. Additionally, they provide insights into the BCI Award submission process, sharing tips for a successful application.
Whether you're fascinated by neuroscience, intrigued by BCI technology, or looking for career inspiration, this episode is packed with valuable knowledge and advice. Tune in to discover how Nick and Maitreyee are revolutionizing the field of neuroprosthetics and making a profound impact on the lives of people with speech impairments.
