Brain stimulator treats depression by beaming magnetic pulses through the skull - Daily Mail 21st October 2008

The pulses trigger small electrical charges that spark brain cells to fire. The stimulator, called ‘Transcranial magnetic stimulation’ or TMS, causes less risk than other methods such as surgically implanted electrodes or the last resort of shock therapy.
