Figure 6.

Effective electric field, E_s, along neurons a1 and a2 (a-b) for both the homogeneous (dashed line) and heterogeneous (solid line) models. The effective electric field is shown at the instant when it is a maximum (maximum time derivative of current of 67 A/μs). The insets show the neurons on their proper position in the cortex. The arrows on the graphics indicate the most important features of E_s (numbers) and the position of the soma (letter “s”). The position along the neuron where these features occur can be seen on the insets.
