¥Surface models are modeled using a set of interconnected nodes
ÐData are mapped to the nodes forming the mesh
ÐSurface models from different subjects have different meshes (i.e.
surfaces are not isotopic) and differing
geometries
ÐCross-subject analysis requires warping the surfaces to match a common
domain
ÐA domain defined by a tessellated sphere and a spherical coordinate system
has been adopted by Caret/SureFit [Van Essen et
al. 1997, 1998 ] and FreeSurfer [Fischl et al.
1999]
