Not sure, whether this posting fits in this category.
I recently used Blender to show students and people interested in neuroscience, how the hippocampal formation (in the rat) looks like. It is basically a tutorial video within Blender in which the strange anatomy of the hippocampus is shown.
At 2:40 you can see another model and the usage of a new add-on that I am about to publish in the next weeks which enables us to model and depict the anatomy of neural projections.
I thought I share this here with you to provide another example of how useful Blender can be for educational purposes.
