brainglobe/brainglobe-heatmap: Rendering anatomical heatmaps with brainrender and matplotlib

brainglobe-heatmap allows you to create heatmaps, mapping scalar values for each brain region (e.g., number of labelled cells in each region) to a color and creating visualizations in 2D (using matplotlib or 3D (using brainrender).

2D heatmap generated using matplotlib - adapted from Fig 1. from Hansen et al (2025)

3D heatmap generated using brainrender

For full documentation, please see the BrainGlobe documentation. Examples can be found in the examples directory of this repository.
