We describe a routine to precisely localize cortical muscle representations within the primary motor cortex with transcranial magnetic stimulation (TMS) based on the functional relation between induced electric fields at the cortical level and peripheral muscle activation (motor evoked potentials; MEPs). Besides providing insights into structure-fu...

Here, we provide an example dataset for our *Precise motor mapping with transcranial magnetic stimulation* protocol. All scripts, installation instructions, etc. to conduct the mapping are made accessible in a code repository.

We describe a routine to precisely localize cortical muscle representations within the primary motor cortex with transcranial magnetic stimulation (TMS). This allows for an accurate and experimenter-independent determination of motor thresholds and enables TMS dosing based on individual field thresholds. Motor evoked potentials (MEPs) for different...

Besides insights into structure-function relationships, this lays the foundation...

Transcranial magnetic stimulation (TMS) is a powerful tool to investigate causal structure-function relationships in the human brain. However, a precise delineation of the effectively stimulated neuronal populations is notoriously impeded by the widespread and complex distribution of the induced electric field. Here, we propose a method that allows...

Background: The precise cortical origins of the electrophysiological and behavioral effects of transcranial magnetic stimulation (TMS) remain largely unclear. Addressing this question is further impeded by substantial inter-individual response variability to TMS. Objective: We present a novel method to reliably and user-independently determine the...
