Deep Brain Stimulation (DBS): Deep Brain Stimulation (DBS) is an advanced neurosurgical procedure in which electrodes are implanted to stimulate targeted regions of the brain and modulate abnormal neural activity. A pacemaker is implanted in the chest pocket that delivers controlled electrical impulses through these electrodes. DBS is a well-established treatment for movement disorders such as Parkinson’s Disease, Essential Tremor, and Dystonia, among others. It has also been reported to benefit a subset of patients with treatment-resistant Tics, Depression, Obsessive-Compulsive Disorder, Epilepsy, and Chronic Pain.
At Dr. Doshi’s Advanced Neuromodulation Research Laboratory, our current focus is to thoroughly examine connectomic DBS. In the last decade, neuroscientists have reported that the outcome of DBS is associated with stimulation of white matter tracts, and hence, tractography may have applications in prospective DBS targeting, programming, and precision DBS. However, given the current state of DWI imaging technology, we are interested in thoroughly evaluating whether connectomic targeting and programming can improve the outcome of DBS.

Non-Invasive Neuromodulation
Non-invasive neuromodulation refers to a group of several approaches used to modulate neurological activity transcranially, i.e., without entering the skull cavity. At Dr. Paresh Doshi's Lab, we currently work with H-coil deep Transcranial Magnetic Stimulation (dTMS) using a BrainsWay™ machine. TMS uses subtle dynamic magnetic fields to induce electrical potential in the neural networks and modulate synaptic plasticity. At JHRC’s Department of Restorative and Regenerative Medicine, we offer TMS to patients with depression, anxiety, obsessive-compulsive disorder, mild cognitive impairment, migraine, and neuropathic pain. Hence, our current research focuses on developing and validating new treatment protocols for the aforementioned conditions.

Computational Neuropsychiatry and AI Integration
In today’s era of technological advancements, computational techniques such as artificial intelligence and machine learning can be extremely helpful to advance the practice of medicine. However, the scientific distance between engineers and doctors often slows the adoption of these techniques into the practice of medicine. At Dr. Paresh Doshi's Lab, we bring engineers to the patient’s bedside to bridge this distance and pursue med-tech innovation.
Our current research focuses on integrating machine learning into DBS Programming to facilitate quicker and targeted DBS Programming for STN-DBS.
