Problem Addressed

Currently, stimulation of deep brain structures to ameliorate treatment-resistant symptoms of psychiatric and neurological disorders can only be achieved through permanently implanted electrodes.  Acoustic, electromagnetic induction, or optical signals have also been explored in the field of neuromodulation, but they are largely absorbed and scattered by surrounding tissues, causing substantial signal attenuation.  In contrast, low-radiofrequency alternating magnetic fields (AMF) offer a convenient form of non-invasive stimulus that can reach deep into the body, even into deep brain regions, due to the weak magnetic properties and low electrical conductivity of tissue.
