Figure 6From: Simulation of epiretinal prostheses - Evaluation of geometrical factors affecting stimulation thresholdsA graphical representation of lateral extent of retinal stimulation. An illustration of the definition for lateral extent of retinal stimulation. It is denoted by a horizontal distance measured at h GL where the threshold electric field criterion is reached for a 20% increase in stimulation amplitude. The dark block represents the stimulating electrode.Back to article page
