Modelling of the Current Density Distributions during Cortical Electric Stimulation for Neuropathic Pain Treatment

Figure 4

Examples of current density () distributions over the axial slices at 4 cm below the projection of Cz over the cortex. Colormaps are set between 0 and the 50% of MCT (i.e., 1.25 A/m²); therefore, white areas correspond to the areas in which is equal or higher to the scale upper limit. Green arrows represent the direction of the current density on the cortex. Panel on the left shows the distribution produced in the cortex by “Reference” simulation.
