Figure1: Schematic structure of the primary visual cortex implemented in Fischer (2007). Simple cortical cells are modeled through log-Gabor functions. They are organized in pairs in quadrature of phase (dark-gray circles). For each position the set of different orientations compose a pinwheel (large light-gray circles). The retinotopic organization induces that adjacent spatial positions are arranged in adjacent pinwheels. Inhibition interactions occur towards the closest adjacent positions which are in the directions perpendicular to the cell preferred orientation and toward adjacent orientations (light-red connections). Facilitation occurs towards coaligned cells up to a larger distance (dark-blue connections).
