A method is disclosed for predicting the stimulation effect of cortical neurons in response to extracellular electrical stimulation. The method comprising the steps of defining an electrode configuration, defining a reconstructed neuronal cell type, wherein the reconstructed neuronal cell is characteristic of the physical and electrical properties of a neuronal cell, computing an electric field potential at the reconstructed neuronal cell, computing an effective transmembrane current of an arborization of the reconstructed neuronal cell, and determining a probability of activation of the reconstructed neuronal cell. A method for inducing an electrical stimulation effect on a cortical column is also disclosed. In an embodiment, the predicted network response of a cortical column is used to configure one or more electrodes to induce cortical stimulation.
