British neuroscientists are working on miniaturizing devices that would be able to deliver high tesla fields to produce magnetic stimulation within the brain, a potential therapy for migraines, and other neurological or psychiatric disorders.
Transcranial magnetic stimulation
Transcranial magnetic stimulation (TMS) is a noninvasive method to excite neurons in the brain: weak electric currents are induced in the tissue by rapidly changing magnetic fields (electromagnetic induction). This way, brain activity can be triggered with minimal discomfort, and the functionality of the circuitry and connectivity of the brain can be studied.
How a magnet turned off my speech
Words failed me. I stuttered as Prof Vincent Walsh turned off the speech centre of my brain for a few thousandths of a second to demonstrate the power of transcranial magnetic stimulation, a popular way to interfere with the most complex known object in the universe.
