The C. elegans 3D model this was derived from was produced by Dr. Christian Grove and Dr. Paul Sternberg at the VirtualWorm project (WormBase, CalTech) and released into the public domain. You can visit the VirtualWorm home page at http://caltech.wormbase.org/virtualworm/ .

This is a work in progress. Please get in contact for more information.
This model is still very much in the early stages of development.
While the individual cell morphologies are in NeuroML, and the connectivity can be generated in neuroConstruct using real connection data, a full spiking model requires much more information about the electrical properties of neurons in C. elegans
This model was originally developed in: Blender
The code for this model is hosted on GitHub: https://github.com/openworm/CElegansNeuroML
