Ultrasound Technology to Decode Brain Activity for Brain Machine Interfaces | – Medgadget

Researchers at Caltech have developed a non-invasive functional ultrasound system that can detect brain activity by listening to tiny changes in blood flow within the brain. The system could provide a viable alternative to invasive electrodes that are implanted into the brain for brain machine interfaces, such as those used in prosthetics. So far, the system can detect the brain activity corresponding to a specific body movement in non-human primates, before the movement occurs.
