Predicted relationships between singularities (colour) and CO blobs (grey) at different retinotopic locations.

A. A set of oriented lines which pass through the centre of the fovea (left) will create a local supragranular map, located in the foveal region of V1 (right), in which the singularity and CO blob coincide (middle).

B. A set of oriented lines which miss the fovea (left) will create a local supragranular map, located in the parafoveal region of V1 (right), in which the singularity and CO blob do not coincide (middle).
