Our research efforts have focused on computational modeling of neural stimulation and circuitry related to devices and therapies used in neuromodulation. These therapies include deep brain stimulation (DBS), spinal cord stimulation (SCS), vagus nerve stimulation (VNS), motor cortex stimulation (MCS), and other related aspects of neural processing. Modeling has included circuitry models of the basal ganglia in Parkinson’s disease and the DBS electrode in a discrete solution, M1 and S1 regions of cortex with cortico-thalamic processing, three-dimensional modeling of the activating function and fibers of passage, and patterns of stimulation and power in tremor control.
More recently, we have focused on mechanisms of action to treat chronic pain using high frequency and burst type spinal cord stimulation as well as work showing how computational models of neural circuitry can be used to help streamline new drug development in major depressive disorder. We have also worked on a new analysis of theoretical changes in information processing in axons of passage through regions using deep brain stimulation in Parkinson’s disease and other disorders. Our work has been presented this past year at the International Neuromodulation Society meeting in Edinburgh, Scotland, the Neuromodulation Society of New Zealand and Australia in Adelaide, Australia, the International Society of Intraoperative Neurophysiology in Seoul, South Korea, the North American Neuromodulation Society meeting in Las Vegas, NV, and the Spine Intervention Society meeting in San Francisco, CA.
In these recent efforts, we have further developed and refined our hypothesis on how high frequency stimulation systems modulate axons, both in suppressing or blocking them as well as in stimulating them. We continue to examine the fundamental mechanisms of neuromodulation therapies, an area of rapidly developing technology and innovation. This work has also been, and continues to be, generously funded by the Sydney Family Foundation in addition to internal funding through the Beth Israel Deaconess Medical Center Department of Surgery.
