Analysis of spatial transcriptomics of a coronal section of mouse brain by Visium H&E. In the first panel, original tissue annotation is given. Tissues are well defined at default resolution for the standard approach. When resolution is decreased to \(\gamma = 0.5\), cells are aggregated breaking the histological types, e.g. cells from the dentate gyrus are merged to the hippocampus. When a nSBM is applied, the structure of the pyramidal layer is maintained at different levels of the hierarchy
