<unk>  <unk>  is a noninvasive form of brain stimulation in which a changing<unk>  field is used to cause electric current at a specific area of the brain through electromagnetic induction. An electric pulse generator, or stimulator, is connected to a<unk>  coil, which in turn is connected to the scalp. The stimulator generates a changing electric current within the coil which induces a<unk>  field; this field then causes a second inductance of inverted electric charge within the brain itself.<unk>  has shown diagnostic and therapeutic potential in the central nervous system with a wide variety of disease states in neurology and mental health, with research still evolving. Adverse effects of<unk>  are rare and include fainting and seizure. Other potential issues include discomfort, pain, hypomania, cognitive change, hearing loss, and inadvertent current induction in implanted devices such as pacemakers or defibrillators.
