An Experimental Evidence of Asymmetrical Distribution of the Electromagnetic Field on Transcranial Magnetic Stimulation Applications

Transcranial Magnetic Stimulation is a therapeutic technique associated with the diagnosis and therapeutic applications of the central nervous system disorders. Parkinson’s disease, depression, schizophrenia and Neuropsychiatry are some of the disease that is commonly treated with TMS. Although this technique has been widely approved for clinical use, relatively little information is recorded in the literature associated with their optimal parameters of the application. Field focalization, electromagnetic field distribution, coil orientation and current direction correspond to some of these criteria. Also, most mathematical and computational studies, for example, are usually based on initial conditions that assuming a symmetrical electromagnetic field distribution.
