Abstract

PURPOSE: The linked quadripolar montage for transcranial electric motor-evoked potentials (qTceMEP) consists of four stimulation electrodes: two linked anodes and two linked cathodes. This montage has grown in popularity because it can result in a larger compound muscle action potential amplitude compared with the conventional bipolar montage. Despite the increasing number of centers adopting qTce…
