Chinese researchers test noninvasive ultrasound brain-computer interface on patients with disorders of consciousness

Teams including the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences present a noninvasive ultrasound brain-computer interface that delivers targeted ultrasound without opening the skull or implanting electrodes.

In a preliminary study with Kunming Medical University, 13 of 24 participants with chronic disorders of consciousness showed clear improvements in conscious behavior after three 20-minute sessions a week for four weeks, according to Pandaily.

The study was small and early. Larger controlled trials would be needed before the approach could be considered an established treatment, and the report mentions no regulatory approval.
