D-WAVE vs MEP

WebD-waves are compound motor action potentials initiated by direct axonal activation and are obtained by a single cortical stimulus. If there is an amplitude decline of more than 50% or a total disappearance of the signal, there is a high probability of severe neurological deficit, e.g., permanent paraplegia [4]. WebD-waves are recorded from epidural or subdural electrodes placed by the surgeon after opening. The initial Direct (“D”) signal seen in cervical and upper thoracic regions corresponds to an initial propagating action potential within corticospinal tract axons. It is triggered in cortical motor neuron axons, probably at a subcortical level. population of hennepin county

Motor Evoked Potential - an overview ScienceDirect Topics

WebIntraoperative neuromonitoring has been shown to be of clinical importance in the surgical resection of IMSCT. The main monitoring modalities include somatosensory evoked potentials, transcranial motor evoked potentials via limb muscles or spinal epidural space (D-waves), and dorsal column mapping. WebD waves represent a neurogram of the CT which is not significantly influenced by nonsurgically induced factors. Stimulation of the CT takes place intracranially distal to the cortical motoneuron body, while … WebSurgical specialties: Neurological, Orthopedic, ENT, Interventional Radiology, Cardiac, Vascular, and Trauma.
