Hi dear francois
i wanted to ask you about the distance between each vertice and the nearest vertice of it. later i create headmodelling with brainstorm (distributed sources) then the output contained the grid locations. the number of grids in my source space is 15002. i calculate the minimum distance between each grids of source space to another but the distance are different!!!!!!!!!. why the minimum distance between each grid and other is different. ???????????????
thanks
Are you referring to the surface tessellation of the cortex? The inter-node distances are adjusted based on the local surface curvature. Areas with high curvature are more finely tessellated than areas that are almost flat, as spatial sampling increases with the local complexity of the surface.
