Table 1.
Current density (μA/cm2) was modeled in a 10 mm diameter sphere within the brain parenchyma directly under the stimulating scalp electrode at sites C3 and F3.

C3 is above the temporal portion of the parietal bone, and F3 is above the frontal bone. The values in the table are mean values for modeled current density at stimulation site targets (C3 or F3) with stimulation currents of 0.5, 1.0, and 2.0 mA, separately for males and females and overall.
