Transcranial magnetic stimulation (TMS) allows to stimulate a given cortical area non-invasively. When applied over the primary motor cortex, TMS yields an electrical response in muscles of the contralateral hand, called motor-evoked potentials (MEPs). Comparing MEPs in different contexts has led to the characterisation of various neural processes including motor inhibition. So far, most studies have exploited single-coil TMS, where data are from only one hand at a time. Recently, a new double-coil TMS method where both hemisphere are stimulated simultaneously has been proposed. Here, we show that this new protocol is reliable to probe motor inhibition bilaterally.
