Model Downloads

Below are instances of models from the reconstructed neocortical microcircuit. The models are made available in the native format in use at the BBP, based on the NEURON simulation package (http://www.neuron.yale.edu).

See the Tools page for instructions on the execution of simulations using NEURON based models.


Models of individual neurons (in the NEURON simulation environment) can be obtained from the me-type fact sheets. A model package contains a morphology file, the ion channel descriptions, the synapse descriptions and templates to instantiate the cell. There is code to construct the model, distribute the ion channels and synapses on the morphology, generate a GUI, and inject current clamp and synaptic input into the model.

The morphology description is a formatted as a Neurolucide ASCII file. The ion channel and synapse description are available as NEURON MOD files. The code for the templates, GUI and simulations is written in the NEURON HOC language or Python. The files containing the synaptic parameters and m-type mappings are tab-separated files.

The complete set of neuron models is available here

You can select specific neuron models in the interface below or by browsing to the relevant me-type fact sheet.

NeuroML2 version

Thanks to a collaboration with Padraig Gleeson of the Open Source Brain, the model packages can be converted to NeuroML2:


A file with the NeuroML2 versions of the model packages is available here
