Query: Normal and Equivolumetric Coordinate Systems for Cortical Areas   We describe coordinate systems adapted for the space between two surfaces,
such as those delineating the highly folded cortex in mammalian brains. These
systems are estimated in order to satisfy geometric priors, including
streamline normality or equivolumetric conditions on layers. We give a precise
mathematical formulation of these problems, and present numerical simulations
based on diffeomorphic registration methods, comparing them with recent
approaches.
