How Does TMS Work?

Transcranial magnetic stimulation uses a coil positioned against the scalp to create brief magnetic fields. Those fields pass through the skull and induce electrical activity in the cortical tissue beneath the coil. The person remains awake, and the treatment does not require anesthesia or surgery.

The location, frequency, pattern, intensity, and number of pulses matter because different stimulation approaches can have different effects on cortical excitability and connected brain networks. For depression, commonly used clinical protocols target the dorsolateral prefrontal cortex. OCD protocols use a different clinical target and treatment framework.

TMS is delivered repeatedly because a single session is not intended to produce the full therapeutic effect. Repeated sessions are used to drive more durable changes in the activity of the targeted network. Clinical response is monitored over the treatment course rather than inferred from the stimulation itself.

TMS is different from ECT. TMS does not intentionally trigger a seizure, does not require anesthesia, and uses focal magnetic stimulation rather than a generalized electrical treatment. It is also different from EEG or neurofeedback: EEG records electrical activity, neurofeedback trains regulation using feedback, while TMS actively stimulates cortical tissue using magnetic pulses.

Neurolimits provides TMS in Austin with clinical screening, individualized treatment planning, progress tracking, and medical oversight. The specific protocol should be selected based on the clinical indication and the individual's circumstances rather than from a generic menu.
