Several studies in animals and humans

Dec 3rd 2013 at 3:59 AM

ImageA small coil that receives an extremely potent alternating electrical current is placed on the human skull in the region of the cortex. Constant change of the orientation of the electric current in the coil is capable of generating a magnetic field that passes through some insulating materials like skin and bones, generating electrical current inside the skull.

Which is able to be focused and restricted to small areas depending geometry and shape of the coil [Hamlet, 2000] When this current reaches the motor cortex, it can produce a muscle response in the contra lateral limb. When TMS is applied to other regions of the cerebral cortex, the results of the function will depend on the chosen area, and then cognitive and emotional effects are possible.

Great article. Thanks.

Several studies in animals and humans

ImageSeveral studies in animals and humans were conducted to evaluate the effectiveness of TMS in the treatment of depression. Such studies, with some surprising results demonstrate that TMS is a promising tool. Nevertheless, the EMT is still experimental, still waiting for further studies to be validated, however, in the future, the EMT can become a powerful tool in diagnosis and therapy in neuropsychiatry.

The authors' goal in this article is to review the basic principles of TMS and discuss the results of studies on the use of this technique in the treatment of depression. INTRODUCTION The human cortex can be stimulated by a non-invasive and virtually painless technique in conscious humans using a pulsed magnetic field. This technique, called Trans cranial magnetic stimulation (TMS or Tran cranial Magnetic Stimulation - TMS), is based on a variable magnetic field.
