Motor Evoked Potentials Improve Targeting in Deep Brain Stimulation Surgery
Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Objectives One of the main challenges posed by the surgical deep brain stimulation (DBS) procedure is the successful targeting of the structures of interest and avoidance of side effects, especially in asleep surgery. Here, intraoperative motor evoked potentials (MEPs) might serve as tool to identify the pyramidal tract.

Cortical EFPs and DRPs are suppressed after pyramidal tract lesions.
, 2013 Averaged EFPs (top traces) and DRPs (bottom traces), evoked by contralateral sensorimotor cortex stimulation, recorded in the L4 spinal cord segment before and after electrolytic lesion of the ipsilateral pyramidal tract at the medullary level.

Image-guided preoperative prediction of pyramidal tract side effect in deep brain stimulation: proof of concept and application to the pyramidal tract side effect induced by pallidal stimulation. [PDF]
J Med Imaging (Bellingham), 2016 International audienceDeep brain stimulation of the medial globus pallidus (GPm) is a surgical procedure for treating patients suffering from Parkinson's disease. Its therapeutic effect may be limited by the presence of pyramidal tract side effect (PTSE).
