The mouse brain coronal and sagittal sections

[MusculusMus]

A really good tool to show gene expression in different organs. My lab work focuses on the mouse brain and we have some region-specific data to plot. After a long time searching, this is the closest R package that fits my purpose. Is it hard to make several coronal and sagittal maps? Then we can add the gene expression value to each region of the brain.

I found another brain-heatmap project 6 years ago brain-heatmap, I want to do a similar thing on ggplot2.

Looking forward to your reply.
