description: Transcranial magnectic stimulation (TMS) is a neurological technique for inducing motor movement by direct magnetic stimulation of the brain’s motor cortex—while the subject is awake and alert—to measure connectivity and excitability. It depends on the principle of mutual induction (discovered by Michael Faraday in 1831), whereby electrical energy can be converted into magnetic fields, and magnetic fields can be converted into electrical energy. The ability to measure the excitability of the motor cortex in important in neuropsychiatry for several 1) TMS may prove valuable as a diagnostic tool, because there is increasing evidence of altered motor cortex excitability in several neuropsychiatric disorders. 2) Stimulus parameters (especially stimulus intensity) must be adjusted to the patient’s individual motor excitability in repetitive TMS (rTMS) treatment protocols. Therefore, the knowledge of how to measure motor cortex excitability is indispensable. 3) Evidence shows that various rTMS protocols can increase or decrease cortical excitability and thus can be used therapeutically to normalize altered excitability in neuropsychiatry. Yet it wasn’t until quite recently—1985 in fact—that the modern age of TMS began. Since then, TMS has played a pivotal role in exploring and mapping previously uncharted regions within the human brain. This comprehensive, extensively annotated volume begins by tracing the history of TMS and then addresses—chapter by chapter—the current applications of TMS in specific disorders including movement disorders, epilepsy, major depression, bipolar disorder/mania, anxiety disorders, developmental stuttering and Tourette’s syndrome, and schizophrenia.
