  Repetitive Transcranial Magnetic Stimulation (rTMS / TMS); a research bibliography

Transcranial magnetic stimulation has also been used to study the mode of action of anticonvulsants and may prove to be a useful means of testing the potential for new drugs to act as anticonvulsants.
Transcranial magnetic stimulation is the noninvasive application of localized pulsed magnetic field to the surface of the skull, to cause a depolarization of neurons in the underlying cerebral cortex (Daryl E., Bohning PH.D.).

Transcranial magnetic stimulation (TMS) is a technique whereby magnetic fields are used to temporarily alter the function of the brain by inducing an electrical current in the brain tissue.
Repetitive TMS (rTMS) can be used either to make the area more active or less active over a specific time period (often 30 minutes or so), while single pulse TMS is used to harmlessly 'knock out' an area for approximately 100ms.
Much weaker magnetic fields (about the strength of a loudspeaker) but much more complex in form, have also been used to induce unusual experiences by stimulating the temporal lobes, most notably by neuroscientist Dr Michael Persinger.
