Transcranial Magnetic Stimulation (TMS) is a non-invasive neurostimulation technique that involves the use of a magnetic field to induce electric currents in specific areas of the brain. This method is used in research to study brain function and connectivity, as well as in clinical applications for conditions such as depression, anxiety, and chronic pain. TMS can be used to stimulate or inhibit neuronal activity in targeted brain regions, providing insights into the role of these areas in various cognitive processes and behaviors. Overall, TMS research aims to better understand the brain and develop therapeutic interventions for neurological and psychiatric disorders.
