Effect of transcranial magnetic stimulation on electroencephalogram activity and emotions

Transcranial magnetic stimulation (TMS) is one of the current approach to stimulate the neurons in the brain, by changing the magnetic fields in that area using electromagnetic induction, neurons with weak signals amplified. Many studies showing that this stimulation can enhance the brain activity,...
