Abstract

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. An array of parallel straight wires was used to measure the inductive effect. The array was placed in parallel planes to the transverse area of the coil, and at various orientations. Preliminary results have shown an asymmetrical distribution associated with the electromagnetic field induced. Such interpretation could provide relevant information about the project and the direction of the induced current for therapeutic applications.
