Neuronal classes How can we scale up models of brain function and make models more accurate and reproducible? 100 billion neurons 100 trillion synapses Specialized networks Synaptic types Input about the body and world Sensations Cognition Actions Electrical Chemical
Conventional model development Experiment Implement the model and tune it Publish 0.10.20.31.0... Clean up
184.108.40.206 220.127.116.11 Requirements I: A culture change – collaborative development Publish 1.0... LAB A Update LAB B 1.1.1 t Update 1.1 LAB C 1.1.3 Update Merge 1.2 Merge
Requirements II: datasets, tools, standardization, and open scientific evaluation Tools for collaborative model development Open source development tools- GitHub Simulators – e.g. Neuron, Brian Applications – e.g. neuroConstruct, Neurokernel, NeuronUnit Standardized model descriptions SBML, CellML, NineML, SpineML Accessibility and critical evaluation ModelDB, BioModels etc Open Source Brain Datasets NeuroMorpho
Pros and Cons of open development and collaboration in neuroinformatics Potential Benefits Scaling up of modeled systems Continuity of projects Improved community resources Development of integrated tool chain Improved scientific value through improved : Reproducibility, Accessibility, Portability Transparency Difficulties/Issues Neuroscience is a competitive system. Vested interests - can we change the prevailing culture? Big investment to develop the tool chain. How will quality be ensured? Will the efforts of the developers be adequately recognized? Are computational neuroscientists ready to expose all the flaws of a model to public scrutiny?

Open collaboration in computational neuroscience Discussion – how to address the issues...? ➢ Neuroscience is a competitive system. ➢ Vested interests - can we change the prevailing culture? ➢ Big investment to develop the tool chain. ➢ How will quality be ensured? ➢ Will the efforts of the developers be adequately recognized? ➢ Are computational neuroscientists ready to expose all the flaws of a model to public scrutiny?
