OBJECTIVE Motor cortex excitability can be measured by transcranial magnetic stimulation (TMS) using different coil types, but paired-TMS was originally devised with a figure-of-eight coil. We asked whether the most popular, circular coil was suited to the every-day assessment of cortical excitability, particularly paired-TMS indexes, and if it reduced the measurement error. METHODS We studied 12 right-handed, healthy subjects (34±7.6 years). Resting motor threshold (MT), cortical silent… CONTINUE READING
