Using TMS to Measure Motor Excitability During Action Observation

2023
Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Transcranial Magnetic Stimulation (TMS) is a non-invasive brain stimulation technique that involves passing current through an insulated coil placed against the scalp. A brief magnetic field is created by current in the coil, and because of the physical process of induction, this leads to a current in the nearby neural tissue. Depending on the duration, frequency, and magnitude of these magnetic...

FAQs
A single stimulation period can alter neuronal excitability in the targeted cortical tissue, while repeated trains extend or reinforce that change. The resulting aftereffects make repetitive TMS useful for examining neural plasticity, meaning activity-related changes in how brain circuits respond. In psychological research, these longer-lasting effects help investigators study consequences that are not limited to the stimulation period itself.
Coil placement determines which cortical region receives the induced electrical current and therefore which neural activity is directly influenced. This focal targeting allows researchers to link a selected brain area with behavior, cognition, or emotion more precisely than a broadly distributed intervention would. Positioning the coil against the scalp over an appropriate region is consequently central to interpreting TMS findings.
Rapidly changing magnetic fields induce electrical currents in cortical tissue, altering the excitability of neurons in the targeted area. The timing and repetition of delivered pulses matter because repeated trains can produce effects that outlast stimulation. These relationships allow investigators to examine how controlled changes in cortical activity influence psychological processes and contribute to broader questions about brain-circuit function.
A typical approach places a stimulation coil against the scalp over a selected cortical region, delivers controlled magnetic pulses, and then evaluates the resulting change in brain activity or behavior. Researchers may use a single stimulation period or repeated trains, depending on whether they are examining immediate effects or longer-lasting changes. The measured outcome is interpreted in relation to the targeted circuit and psychological function.
TMS can temporarily change activity in a targeted cortical area while researchers observe effects on behavior, cognition, or emotion. If altering that region changes a psychological outcome, the result can provide evidence that the associated circuit contributes causally to the function being studied. This approach extends beyond correlational observation by experimentally manipulating neural activity during psychological investigations.
In psychology, TMS supports studies of cognition, emotion, neural plasticity, and the relationship between brain circuits and behavior. Repetitive protocols are also used to investigate or treat conditions such as depression. Its value comes from combining controlled, focal stimulation with observable psychological outcomes, allowing the same general technique to contribute to both basic research and clinical intervention.
