Cylinderization of a representative laminar voxel assigned to layer 7 of study eye 7. Upper: All laminar voxels within laminar layer 7 of the precylinderized lamina are assigned a polar coordinate (Dv, θ) where Dv is the distance along the midlayer reference surface (red) from the neural boundary centroid spline (red dots) centroid (blue dot) and Ds is the radial distance along the surface of the midlayer reference surface from the centroid to the neural boundary (yellow). Lower: Within cylinder layer 7, θ is held constant, but r is proportionally adjusted using the precylinder ratio of Dv/Ds and the cylinder radius of 750 um. Distances Dv and Ds are calculated along a precylinderized reference layer surface contour (curve) that is obtained for every LC voxel. It is not a straight-line measurement in a plane.
