Reliability of Motor Evoked Potentials Induced by Transcranial Magnetic Stimulation: The Effects of Initial Motor Evoked Potentials Removal
Introduction: Transcranial magnetic stimulation (TMS) is a useful tool for assessment of corticospinal excitability (CSE) changes in both healthy individuals and patients with brain disorders. The usefulness of TMS-elicited motor evoked potentials (MEPs) for the assessment of CSE in a clinical context depends on their intra-and inter-session reliability. This study aimed to evaluate if removal ...

متن کاملHuman Motor Cortex Function Characterized by Navigated Transcranial Magnetic Stimulation
Transcranial Magnetic Stimulation (TMS) can be used to assess corticospinal, corticocortical and cortico-subcortical network physiology and function. In the motor system, TMS-induced cortical activation leads to peripheral muscle responses. Various motor functions can be characterized extensively by applying specific stimulation protocols. However, the clinical applications are limited by large...
متن کاملNavigated transcranial magnetic stimulation in preoperative planning for the treatment of motor area cavernous angiomas
Since the introduction of microscopic techniques, radical surgery for cavernous angiomas has become a recommended treatment option. However, the treatment of motor area cavernous angioma represents a great challenge for the surgical team. Here, we describe an approach guided by frameless neuronavigation and preoperative functional mapping with transcranial magnetic stimulation (TMS), for surgic...
متن کاملOnset Latency of Motor Evoked Potentials in Motor Cortical Mapping with Neuronavigated Transcranial Magnetic Stimulation
Cortical motor mapping in pre-surgical applications can be performed using motor evoked potential (MEP) amplitudes evoked with neuronavigated transcranial magnetic stimulation. The MEP latency, which is a more stable parameter than the MEP amplitude, has not so far been utilized in motor mapping. The latency, however, may provide information about the stress in damaged motor pathways, e.g. comp...
