Treatment-Resistant Depression: Results of Latest Electromagnetic Stimulation Study Show Promise
... "rTMS involves passing current through an electromagnetic coil togenerate a magnetic field," they explain. "The magnetic field acts as themedium between electricity in the coil and induced electrical currents in thebrain. The current depolarizes neurons in the brain up to a depth of about twocentimeters b......clei in molecules. Followingan excitation pulse of electromagnetic radiation, the nucleireturn to their original state and give off a signal that can bemeasured and analyzed, showing scientists where the molecules arelocated.
