Field modeling

The strength and spatial distribution of the stimulating field induced in the brain is a key determinant of the effects of noninvasive brain stimulation. We use finite element modeling to characterize the electric and magnetic fields induced in the brain by various transcranial stimulation modalities including transcranial magnetic stimulation (TMS), electroconvulsive therapy (ECT), magnetic seizure therapy (MST), transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS), and transcranial static magnetic stimulation (tSMS). Such information is useful in interpreting clinical results with existing stimulation paradigms and in optimizing the stimulation parameters.
