Cascaded Intracortical Inhibition: Modeling Connection Schemes on a Large Scale Simulator
Receptive field properties of simple cells in the primary visual cortex arise partly from the connection structure of the input paths from the LGN and within the visual cortex. We briefly present our modeling setup used to study various connection schemes, such as spatially opponent inhibition. In spite of its ability to explain certain receptive field properties, severe conceptual difficulties are associated with the biological implementation of the model. We introduce a new cascade-like connection scheme, which largely overcomes these problems and produces more realistic simulation results.
