Cortical column in sulcal wall: A simplified schematic representation of the cortical column in the sulcal wall. Included are neural elements (P2, P3, P5) that are possibly stimulated by the electric field component aligned with the axis of the cortical column. The electric fields perpendicular (Eperp) and tangential (Etan) to the sulcal wall are represented by red arrows.
