Sources of the N15 TMS-evoked potential following motor cortex stimulation localize rostrals to TMS-induced electric fields and depend on dose
Abstract Transcranial magnetic stimulation (TMS) elicits characteristic cortical responses known as TMS-evoked potentials (TEPs) measured via electroencephalography (EEG). An early negative peak can be consistently evoked over the motor cortex at around 15 ms (N15). It remains elusive whether N15 overlaps with the cort...
