Biomedical engineer Chethan Pandarinath and a multi-university team are using brain-computer interfaces to help paralyzed patients, such as those with ALS or stroke damage, communicate and interact with the world.
The technology can differentiate between imagined speech and internal thoughts, offering new ways for patients to express themselves without physical movement.
Researchers are studying brain regions responsible for both speech and hand movement, aiming to create seamless transitions in brain-computer interface controls for activities like moving a computer pointer or speaking.
The goal is to simplify interaction by recognizing high-level intent — such as the desire to click on something — and minimizing the need for step-by-step mental commands.
