Explore neurosurgical targets for chronic pain management in this conference talk by Dr. Jean-Philippe Langevin at the UCLA Neurosurgery Update 2019. Delve into the neuromatrix theory of pain, body representation, and pain as a sensory-emotional-cognitive experience. Examine neuromodulation techniques including cortical stimulation, thalamic stimulation, and periventricular gray matter stimulation. Learn about surgical techniques, somatotopic organization, and neurophysiology of various brain regions involved in pain processing. Discover how diffusion tensor imaging (DTI) may improve surgical outcomes. Investigate the role of the dorsal anterior cingulate cortex in pain perception. Gain insights into emerging diagnostic and treatment modalities for chronic pain based on UCLA Neurosurgery's world-class expertise.
