p392fig11.30 Multiple scales interact with bipole cells that represent multiple depths, and conversely.  See the text for details.<BR>||  How multiple scales vote for multiple depths. Scale-to-depth and depth-to-scale maps. Smallest scale projects to, and receives feedback from, boundary groupings that represent the furthest depths. Largest scale connects to boundary groupings that represent all depths.  multiple-[depth, scale] dot [grouping, filter] cells. [small <-> large] vs [far <-> near]
