Now the only reason why the brain would use an explicit spatial representation would be if it could make use of the spatial aspect of that representation to perform spatial computations in a spatial medium. For example translation, rotation, and scaling can be performed by physically copying the solid volume voxels from one location to another, following the field lines of a global transformation field characteristic of the chosen transformation, expressed in explicit spatial form as a vector field in volumetric space.
