• The Utility of Crossover Motor Evoked Potentials

    Unilateral motor cortex stimulation produces motor-evoked potentials (MEPs) on the opposite side of the body (contralateral) relative to the stimulated cerebral hemisphere. When MEPs are also recorded from the same side of the body (ipsilateral), we sometimes refer to them as “crossover” MEPs. Many people record from both sides of the ...

  • Understanding Anodal and Cathodal Stimulation

    Whether you practice neurophysiology in surgery, in the lab, or in the clinic, you probably use electrical stimulation to activate the nervous system on a daily basis. As you probably know, cathodal stimulation works best in some applications, while anodal stimulation works best in other applications. Armed with this knowledge, ...

  • Intraoperative Mapping of Speech & Language Function

    Intraoperative identification of brain regions that subserve speech & language functions is important during surgical procedures that place these regions at risk for iatrogenic injury. Commonly, the surgeon endeavors to extract a tumor, or abnormal brain tissue that causes intractable seizures, while also preserving eloquent cortex. Damage to language centers can result ...

  • Optimizing Spinal Cord Stimulator Placement with Neuromonitoring

    Spinal cord stimulation (SCS) involves delivery of therapeutic doses of electrical current to the spinal cord for the management of neuropathic pain. The most common indications include post-laminectomy syndrome, complex regional pain syndrome, ischemic limb pain, and angina (Falowski, Celii & Sharan, 2008). There are numerous methods for placing a SCS system, depending on the needs ...

  • 14 Ways to Reduce Needle Sticks in the OR

    Despite the many benefits of neuromonitoring, it is a fact that surgery gets more complicated whenever we are involved in the case. Patient prep time increases, anesthetic requirements change, there’s more people and equipment in the room, the risks are altered and additional consents are required. The risks associated with ...
