Deep Brain Stimulation

Researchers at the University of California, San Francisco (UCSF), a public research university known for its neuroscience work, had two Parkinson's disease patients train at home with a brain-computer interface (BCI) airplane-simulator game, learning to down-regulate cortical beta activity and thereby control the intensity of their own deep brain stimulation (DBS). The work, posted as a preprint on medRxiv on August 17, 2026, points to BCI applications in neuromodulation and to more personalized treatment for Parkinson's and other conditions; its conclusions have not yet been peer reviewed.

A multicenter trial has begun in China to test closed-loop brain-computer interface neuromodulation for treatment-resistant depression, run jointly by the Shanghai Mental Health Center and two Beijing hospitals, Anding Hospital and Xuanwu Hospital. The study will compare closed-loop deep brain stimulation and transcutaneous auricular vagus nerve stimulation against sham stimulation, enrolling patients who have responded inadequately to standard antidepressant treatment. It uses a patient-preference design with randomized assignment within each intervention group.
