"It is more like an electronic doctor about the size of a matchbox was implanted under the patient's skull to monitor brain activity in real time, helping precisely intercept epileptic seizures before they occur," Guo said.

"The successful application of ANS technology signifies the beginning of a new era of precise neuro regulation in the field of epilepsy treatment," he said. "It is not only a significant breakthrough in bringing brain-computer interface technology from the laboratory to clinical operation, but also offers a new treatment pathway for patients with drug-resistant epilepsy, helping effectively reduce the frequency of seizures."

Since the girl's surgery, the hospital has planned to recruit more patients for a clinical trial study of implantable closed-loop brain ANS technologies for the treatment of drug-resistant epilepsy.
