TMS methods

The application of TMS in cognitive neuroscience carries a variety of technical and interpretative challenges.

As a neurostimulation method, one critical issue is the control of TMS intensity. What strength of TMS is sufficient to yield effective (but not excessive) stimulation of cortical tissue?

We have found that the extent of cortical activity during TMS is steeply related to the distance between the scalp and cortex.

Even a difference of 1mm in the scalp-cortex distance between different sites can have a measurable and reliable effect on TMS-evoked behaviour.

We have therefore developed a scaling method for calibrating the intensity of TMS according to scalp-cortex distance, thus enabling more precise and comparable stimulation of different regions.
