Surfaces	Utility	Reference
Grey and white	Initialisation and visualisation	Lewis et al., 2014
Layer 1/2 and layer 4	Boundary conditions	Wagstyl et al., 2018a
Equivolumetric	Staining intensity profiles	Waehnert et al., 2014
Deep learning laminar	Laminar thickness	Wagstyl et al., 2020
Hippocampal	Initialisation and visualisation	DeKraker et al., 2019
