Third electrode pair can sharpen deep brain stimulation technique, mouse experiments suggest

Article excerpt

Researchers at the University of Geneva and ETH Zurich have found that adding a third electrode pair can substantially improve the precision of deep brain stimulation, a noninvasive technique used to treat neurological and psychiatric disorders. Using mouse experiments, the team demonstrated that this refinement allows clinicians to target brain regions with greater accuracy, potentially reducing unwanted side effects and expanding the therapeutic applications of the technology. The findings suggest a straightforward hardware modification could make an established treatment significantly more effective.
