 I'd like to demonstrate a few things from ModelDB at the 2012 Society for Neuroscience meeting. This is the homepage of ModelDB and one thing we're very proud of is the increased number of cell types that have grown in our database over the years. We have a long list of vertebrate cell types and then we also have at the bottom several invertebrate cell types from various organisms and if we click on one of these cell types, for example, the CA1 pyramidal neuron, you can see a list of contributed models and we can re-display the model names with descriptions which can help a modeler find a model that's of interest to them and one can click on the model name and go to the show model page which then shows the name of the model, very short summary of the model, the reference the model is associated with and for neuron models with the neuron simulator one can also, if one has neuron installed, start up a simulation that will enable one to run the model on the computer and so I'm just starting up a model from 1995 and one can just see how the model runs in its default parameters, one can go in and change parameters and we run the model to explore other ranges of parameters and that can be done graphically or just by downloading the model and changing the computer code. I'd like to show a couple of other things, the process of having models in a database is helpful going back to the home page because curation is a lifelong process for a model because the models keep changing over time in the sense that the simulators that the model was created to run in can change so it is helpful to have models in a version control system that you can then update the model where people have supplied bug fixes and sometimes also the as I was saying the simulator gets updated and then the model has to be updated to keep running. The version control system you can see how the models have changed for the change set, a color change set so that's also helpful.
