Hybrid FEM-NEURON model development. The steps executed to develop the model are summarized: nerve anatomy is segmented, and then extruded to obtain the 3D realistic model of the nerve. The electrodes are merged inside, and the inverse model computed. In NEURON, the activities of the involved fibers are computed and then merged together with FEM-solutions, to reconstruct the activity, which would be captured from the metal microelectrode
