A primary task of the retina is to frequency encode light absorption into action potentials. Using simulated artificial neural networks (SANN), the direction selective component of these electrical signals was replicated. The SANN was constructed to mimic the retinal architecture and was trained using published extracellular recordings from ganglion cells. Analysis of the trained model supported the hypothesis that Direction Selectivity arises from asymmetric connections among retinal cells. This project contributes to development of a biology-inspired artificial vision solution.
