Selectivity of conventional electrodes for recording motor evoked potentials: An investigation with high‐density surface electromyography

The objective of this study was to determine whether motor evoked potentials (MEPs) elicited with transcranial magnetic stimulation and measured with conventional bipolar electromyography (EMG) are influenced by crosstalk from non‐target muscles.
