A Python package and an addon that takes a NEURON simulator model and exports its 3D structure and membrane activity to Blender. The export can be peformed via NEURON GUI or via Python commands.
The tool is integrated with NEURON to provide a simple user interface and a set of Python commands that can be used to visualize and inspect single cell or network morphology and activity.
Install Steps and Documentation
Instructions for how to install and use BlenderNEURON can be found here: BlenderNEURON Documentation
Example Cells and Activity
|Neocortex Layer 5 Pyramidal Cell||Hippocampus CA1 Pyramidal Cell|
|Cerebellum Purkinje Cell||Neocortex Layer 5 Basket Cell|

Virtual slices can be created by manipulating Blender’s camera clipping distances. An example of a virtual slice of an olfcatory bulb model (colors represend different cell types):

Interactive models can be embedded in websites
Exported models can be saved as .blend files and uploaded to 3D model sharing websites like Sketchfab.com. The uploaded model can be embedded in websites which allows aspects of the model to be explored interactively without any software.
