Gyral net: A new representation of cortical folding organization

Illustration of the concept of gyral net and gyral joint. (a) Reconstructed cortical surface color-coded by gyral altitude. (b) Extracted gyral net. (c) Zoom in view of the circled area in (b). In this paper, we propose a new representation of cortical gyri/sulci organization pattern - gyral net, which models cortical architecture from a graph perspective, starting with nodes and edges obtained from the surface reconstructions.141
