How TMS works

Doctors can use TMS to find out how different parts of the brain are wired together. To carry out TMS, a magnetic coil is held over a person's head. A rapidly changing magnetic field passes through the skull, and causes small electric currents to flow in parts of the brain. TMS can be used to produce effects by disrupting normal brain activity - such as making muscles twitch.
