Non-invasive brain stimulations mainly consist of repetitive transcranial magnetic stimulation and transcranial direct current stimulation. Repetitive transcranial magnetic stimulation exhibits satisfactory outcomes in improving multiple sclerosis, stroke, spinal cord injury and cerebral palsy-induced spasticity. By contrast, transcranial direct current stimulation has only been studied in post...

As important non-invasive techniques in brain stimulation, transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) have been studied and compared in this paper by employing impedance method and a 3D human head model. The quantitative analysis of distributions of current density and electric field by tDCS and TMS have been presented. Results are compared and po...
