A new paper published in Nature Reviews Neurology suggests that recent advances in deep brain stimulation (DBS) for Parkinson disease could lead to treatments for conditions such as obsessive-compulsive disorder (OCD), Gilles de la Tourette syndrome and depression. The authors of the paper, from the Geneva University Hospitals (HUG), University of Geneva, University of Tübingen and the Wyss Center for Bio and Neuroengineering, argue that bi-directional electrodes which can both stimulate and record from deep brain structures — known as closed-loop DBS — could have applications beyond Parkinson disease.
Other bi-directional brain-computer interfaces (BCIs) have been in development in recent years, notably for the real-time signal processing of neuronal activity to allow control of a robotic arm directly from the brain in people with paralysis.
Professor John Donoghue, Director of the Wyss Center: “Interestingly the fields of brain-computer interfaces for movement restoration and deep brain stimulation for Parkinson disease have developed largely independently. Deep brain stimulation researchers tend to be neurologists or neurosurgeons while brain-computer interface researchers are often neuroscientists, roboticists and engineers. By working together and sharing information we can learn from each other and potentially expand the reach of this technology so that it can help more people.”
