Table 4.

Efficient volume choices for 10 and 5 percent differences based on median current density comparisons to 100% models for Anisotropic (top) and Isotropic (bottom) cases volume for three electrode configurations T7-T8 (blue), F3-RS (green), Cz-Oz (purple). Dark shaded values correspond to presumed tissue targets for each electrode configuration
