The Science Behind TCeMEPs: Transcranial Electrical Motor Evoked Potentials. Part 1

In the Intraoperative Neurophysiological Monitoring (IONM) world, few tools are as crucial to providing real-time motor function assessment as Transcranial Motor Evoked Potentials (TCeMEPs). They provide neurophysiological assessment of the motor fibers to assist clinicians in monitoring the integrity of the descending motor pathways, namely the corticospinal tract responsible for voluntary motor sequences. TCeMEPs are used throughout various procedures, such as during complex spine surgeries, brain tumor resections, brainstem surgeries, and any procedure involving the potential for motor function integrity loss.
