How TMS works in the brain
A magnetic coil placed against the scalp generates brief, rapidly repeating magnetic fields. Those fields pass painlessly through the skull and induce a small electrical current in the cortex directly beneath the coil. Repeated over a course of treatment, this stimulation increases activity and connectivity in the mood-regulating network anchored by the DLPFC — a process closely related to neuroplasticity, the brain's ability to strengthen healthier circuits over time.
