In other words, unlike neuroimaging methods such as functional magnetic resonance imaging (fMRI) that indicate correlations between brain and behavior, TMS can be used to demonstrate causal brain-behavior relations. ... As a result, TMS has become an important tool in cognitive neuroscience.

Is TMS causal?

A TMS coil induces an electric field which might influence the activity of brain tissue. ... Thus, TMS is often considered to be an extension of neuroimaging, which (due to its influence on brain activity) allows causal relations to be tested. TMS is frequently used to decompose the functional organization of the brain.

What does an TMS show?

Transcranial magnetic stimulation (TMS) is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression.
