Transcranial magnetic stimulation (TMS) is method of brainneurons stimulation by alternating magnetic field and measuringmotor-evoked potentials (MEPs) with electromyography monitoring.Recently, some new technologies were introduced, basedon classical TMS, which allowed noninvasive brain mapping ofcortical motor areas. Navigation transcranial magnetic stimulation(nTMS, NBS eXimia Nexstim) is one of them. In this articlewe describe our experience of m. abductor pollicis brevismotor area mapping in 29 healthy volunteers. Basic parametersof TMS were measured: MEP amplitude (408.49216.36 uV),latency (22.380.97 ms), passive motor threshold(40.084.68% for the left hemisphere, 48.719.16% for theright hemisphere). Maps of cortical areas were builded.
