Towards community developed cerebellar granule cell models

----------------------------------------------------------

This project was started following the [2013 OSB kickoff meeting](http://www.opensourcebrain.org/projects/osb/wiki/Meetings). At that meeting it was decided that the development of individual cell models from the cerebellum would be a good test case for exploring the requirements on technical infrastructure and the social aspects of collaborative model development. Due to the many independent granule cell layer networks being developed by participants at the OSB meeting, the cerebellar granule cell was identified as a good first cell model to focus on.

This wiki is intended to help gather the following information/requirements:

-   What granule cell models are out there?

-   What electrophysiological properties do labs wish to reproduce in their models?

-   What experimental data is publicly available on the behaviour of the granule cell?

-   How well do existing models reproduce these behaviours?

Models of the cerebellar granule cell

### Models on OSB

Target electrophysiological properties of granule cells

-------------------------------------------------------

To facilitate comparison between granule cell models it would be good to quantify certain properties of the cell activity which labs find **in their experimental data** and which should be reproduced in models. An initial list of properties is:

-   Resting Potential

-   Input Resistance

-   Reversal potential of Na

-   Reversal potential of K

-   AP max depolarisation

-   Firing rate at ?? Hz

-   Total cell capacitance

-   Soma radius

-   More…

Different species, drugs, experimental conditions will lead to different values for these between labs. Nevertheless, it would be good to get input from as many labs as possible.

Information on construction of tests for comparing model behaviour to experimental data

Much of this will be based on [NeuroUnit/SciUnit](http://www.opensourcebrain.org/projects/neuroelectrosciunit) and existing test scripts in neuroConstruct projects (e.g. [here](https://github.com/OpenSourceBrain/GranuleCell/blob/master/neuroConstruct/pythonScripts/RunTests.py)).
