Caltech Develops Ultrasound Method to Decode Brain Intentions Non-Invasively

Researchers at Caltech developed a technique using ultrasound to interpret the brain's intentions without requiring invasive procedures. The method offers a less intrusive alternative to existing brain-computer interface approaches that typically involve implanted electrodes. The research, published in 2021, aims to advance the field of neural decoding by leveraging ultrasound imaging of brain activity. This approach could have significant implications for assistive technologies helping people with movement disabilities. The study represents a step toward safer, more accessible brain-machine interface solutions.
