APPARATUS AND METHOD FOR TRANSCRANIAL MAGNETIF BRAIN STIMULATION, INCLUDING THE TREATMENT OF DEPRESSION AND THE LOCALIZATION ND CHARACTERIZATION OF SPEECH ARREST

An apparatus and method for transcranial magnetic brain stimulation. The apparatus allows transcranial stimulation at higher power efficiency and lower heat generation than prior available magnetic stimulator coils without an iron core. Use of the apparatus allows an improved method for active localization of language function. The device can also be used in rapid rate transcranial magnetic stimulation for the treatment of depression.
