Topology-preserving smoothing of retinotopic maps
Fig 1
Illustration of topological and non-topological maps.
(A) A polygon patch on an inflated cortical surface (source domain). (B) A topological mapping of (A) in the target domain (retina space). It preserves the structure of the source polygon. (C) A non-topological mapping of (A). It breaks the structure of the source polygon: fi is moved out of the edge , resulting in what is called a flipped triangle Δfifjfk. (d) A typical retinotopic map of V1. Flipped triangles are labeled with red color.
