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.

Example Cells and Activity

l5pyr hipca1
Neocortex Layer 5 Pyramidal Cell Hippocampus CA1 Pyramidal Cell
purk l5basket
Cerebellum Purkinje Cell Neocortex Layer 5 Basket Cell

Example Networks

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):

Example visualizations of an olfactory bulb model (Migliore et. al. 2014).

60MCs A network of about 60 mitral cells

5MCs 3D structure and activity of a 5 mitral cell network and several accompanying granule cells

1MCs Activity of 1 mitral cell with several hundred companion granule cells

Interactive models can be embedded in websites

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