Scientists based at Imperial College London in the UK are working on a non-invasive way of delivering deep brain stimulation (DBS), they announced at the Society for Neuroscience conference in San Diego, USA. The non-invasive deep brain stimulation works by placing two electrical fields of different frequencies outside the head. The team have tested the technique in mice, as well as on healthy human volunteers.

DBS traditionally requires invasive and risky surgery to implant electrodes deep in the brain. Originally developed thanks to research in primates, DBS is used as a treatment in Parkinson's disease. More research is needed to refine the method to become as specific and to reach as deep as conventional DBS does (Source: EARA).
