Assessment of the similarities and differences between all 11 volume conductive modelling approaches when investigating only the medial sources. (A–C) The median relative error between pairs of models represented in matrix form. Here errors are displayed when current flow is modelled in all three cardinal orientations (A), only sources oriented right–left (B) and inferior–superior (C). (D–F) The median correlation coefficient (squared) between pairs of models for all orientations (D), right–left (E) and inferior–superior (F). (G-I) Both the relative and correlations plotted, but this time between the Finite Element Model (FEM) and all other models for all orientations (G) right–left (H) and inferior–superior (I). Black dashed line shows the boundary between models containing bone (right of line) and not.
