Hi I have read (Dale, Fischl et al. 1999) and (Fischl, Sereno et al. 1999) . I have a question about if I understood the tessellation procedure right. There are two vertexes in each voxel, but is the total number of vertex constant across brains. I believe that number of total vertex does not change over brain since it will be difficult to do statically measure if the total numbers of vertex change. Nevertheless, the shape and size of the vertex do change. Is this a correct assumption?
