Intersession reliability of fast motor mapping using TMS

The organization of the primary motor cortex (M1) can be non-invasively assessed using transcranial magnetic stimulation (TMS) combined with frameless neuro-navigation. By delivering single pulses of TMS over M1 and recording the motor evoked potentials (MEP) from target muscles, the location and size of muscle representations can be obtained to create a “motor map” [1]. Characteristics such as area, volume, and center of gravity (CoG) are quantified from motor maps. Motor mapping typically requires upwards of 30 minutes to complete which reduces its utility in time-sensitive contexts.
