Video Summary

In this video, Ms. Arati Minnesundaram, a third-year medical student at Tufts Medical, presents on the electrophysiological mapping of cortical networks activated by dorsal versus ventral subthalamic deep brain stimulation (DBS). DBS is used to improve motor symptoms in treatment-resistant Parkinson's disease, but it is important to differentiate the networks being stimulated. The study used source localization of evoked potentials and analyzed data from subjects who had undergone DBS. The results showed that dorsal stimulation preferentially activates the motor cortex, while ventral stimulation leads to more widespread activity. Additionally, the study found occipital lobe activation in patients with globus pallidus internus (GPI) stimulation. The presenter discusses the need for further research and expresses gratitude to the Harrington Lab at MGH and the Eskindar Lab for their support.<br />Credits: Ms. Arati Minnesundaram (presenter), Harrington Lab at MGH and Eskindar Lab (support), Parkinson's Disease Summer Student Fellowship (funding)
