Connectivity data for the cortical visual system of the macaque monkey, rearranged from Felleman & Van Essen (1991). Different colors and symbols in this table represent different types of structural links that connect these 30 cortical areas with each other. The table's information is meant to be read: source area in the left column has […] connectional relation with target area in the top row. Ø - signs stand for links that have been explored experimentally, but were found to be absent; x signs and light grey shading indicate existing connections for which no further qualifying information was available; < and > signs stand for feedforward and feedback connections, respectively; = denote lateral connections; = and = signs show 'mixed' feedforward/lateral or feedback/lateral links, respectively. For easier recognition, connections of a feedforward type are additionally indicated by blue shading, feedback connections by yellow and lateral by green shading. This classification of types relates to patterns of connections between different cortical layers, as explained in more detail in Section 5. Question marks and lighter colors point out information that has been classified as less reliable by Felleman & Van Essen (1991); finally, empty slots indicate experimental information not yet available in this compilation. Areas MIP and MDP have been excluded, because of the limited information available for them. For area abbreviations refer to Felleman & Van Essen (1991).
