Transcranial magnetic stimulation (TMS) is method of brain neurons stimulation by alternating magnetic field and measuring motor-evoked potentials (MEPs) with electromyography monitoring. Recently, some new technologies were introduced, based on classical TMS, which allowed noninvasive brain mapping of cortical motor areas. Navigation transcranial magnetic stimulation (nTMS, NBS eXimia Nexstim) is one of them. In this article we describe our experience of m. abductor pollicis brevis motor area mapping in 29 healthy volunteers. Basic parameters of TMS were measured: MEP amplitude (408.49±216.36 uV), latency (22.38±0.97 ms), passive motor threshold (40.08±4.68% for the left hemisphere, 48.71±9.16% for the right hemisphere). Maps of cortical areas were builded.
