About

Patricia W. Freeman is a leading figure in the field of stereotactic and functional neurosurgery, with a primary focus on optimizing deep brain stimulation (DBS) for movement disorders. Her research centers on the intersection of surgical robotics, neuroimaging, and intraoperative physiology to enhance the precision and safety of DBS electrode placement. Freeman’s most-cited work, "Electrode Placement Accuracy in Robot-Assisted Asleep Deep Brain Stimulation" (2019), with 42 citations, represents a landmark contribution by demonstrating that robot-assisted, asleep DBS can achieve submillimetric accuracy comparable to traditional awake procedures. This finding has significant clinical implications, reducing patient discomfort and operative time while maintaining high targeting reliability. Beyond this study, Freeman has advanced the understanding of how electrode positioning influences therapeutic outcomes, particularly in the subthalamic nucleus and globus pallidus. Her work has been instrumental in validating robotic systems as a standard tool in DBS surgery, influencing protocols at major medical centers. Freeman’s contributions are widely recognized for bridging engineering precision with clinical neurosurgery, making her a key innovator in the evolution of minimally invasive, image-guided interventions for Parkinson’s disease and essential tremor.
