Transcranial Magnetic Stimulation
Pronunciation: trans-KRAY-nee-al mag-NET-ik
Also written as: TMS — Transcranial Magnetic Stimulation
Non-invasive neuromodulation technique using magnetic fields to stimulate specific brain regions.
Full Definition
Transcranial Magnetic Stimulation (TMS) is a non-invasive neuromodulation procedure that uses magnetic fields to stimulate nerve cells in specific areas of the brain. A magnetic coil placed against the scalp generates brief magnetic pulses that pass through the skull and induce localized electrical currents in cortical neurons. TMS can be delivered as single pulses, paired pulses, or repetitive trains (rTMS). The technique is used therapeutically for depression, migraines, and other psychiatric conditions, and as a research tool for studying brain function and cortical connectivity.
Usage
Usage note: Distinguish from other transcranial stimulation methods; magnetic field is the key differentiator.
