This Chinese Startup Wants to Build a New Brain-Computer Interface—No Implant Required | WIRED

Gestala, a Chinese startup, aims to develop a noninvasive brain-computer interface using ultrasound technology. Unlike traditional brain-computer interfaces that rely on invasive implants, Gestala plans to stimulate and eventually read from the brain using focused ultrasound. The company's initial focus is on treating chronic pain by targeting the anterior cingulate cortex, a brain region involved in the emotional component of pain. Future plans include expanding to other indications such as depression, stroke rehabilitation, Alzheimer’s disease, and sleep disorders.
