1. Development of NeuronBank v2.0 Akshaye Dhawan B&B Fellow Department of Computer Science In collaboration with the Neuroscience Institute

2. http://www.cajal.csic.es/V Understanding the brain requires understanding its circuitry

3. Problem: We are using publications as a method to catalog neurons and neural circuits Information is distributed and fragmented. No means to efficiently search this knowledge. No means to publish incremental knowledge without a functional story.

4. Neuromics Genomics is the study of the Genome, where the Genome consists of all of the genes in an organism Neuromics is the study of the Neurome, where the Neurome consists of all of the neurons in an organism

5. The Neurome is harder to represent than the Genome. Neurons are identified based on their properties. –Idiosyncratic –Species-specific –Constantly evolving

6. The Neurome is harder to represent than the Genome. No standards for representing our knowledge of neural circuits. No means to database this knowledge

7. Our Approach Traditional databases are not a good fit - Changes in representation would cause the database schema to change Ontology: A formal representation of a set of concepts within a domain and the relationships between those concepts – A Vocabularydomain We created a core ontology that applies to all nervous systems We also support extensible species-specific ontologies.

8. NeuronBank is to neurons what GenBank is to genes. –A place to publish knowledge about neurons and neural connectivity –Tools to represent, search, analyze, and share knowledge of neurons and neural circuitry. –Collection of ontologies and tools to access them NeuronBank.org: A Neuromics Tool

11. DSI NeuronBank.org: A Neuromics Tool

12. DSI NeuronBank.org: A Neuromics Tool

19. So what else have we been up to? Stable version out on www.neuronbank.org www.neuronbank.org Efforts underway to: –Make our data useful to a larger community –Expand NeuronBank to other species Summer 2008, Leech Ontology Meeting, Woods Hole, Ma

20. Lesson 0: (Obvious) Cross-Disciplinary Challenges Different disciplines Different cultures/languages Reward: The satisfaction of working on real problems Key: Realistic expectations.

22. Lesson 1:Defining Requirements Requirements describe in detail what a software system is supposed to do Easier said than done The Myth of Stable Requirements –Specially true in a research project such as this –Give and take of size/scope through the funding process

23. Example: NeuroViz Moved from a 3D program to a 2D web browser based applet That:

24. Became this

25. NeuronBank v2.0 NeuronBank 1.0 achieved its objectives. First system to: –Support a varying data model for Species specific representation –While still allowing searches across species At the time of commencing work on v1.0 no clear standards existed for storing data as per our requirements

26. Problems with v1.0 Since v1.0 a lot of research has gone towards realizing the Semantic Web Extension to the WWW where the semantics of the information is defined We used a combination of technologies to build v1.0 This works… But: –Standards have now emerged for the Semantic Web (OWL) and Biological Ontologies (OBO). We need to conform to these. –Development Challenges. –Interface problems.

27. Project updates Aim to bring the data in NeuronBank into the Open Biomedical Ontologies (OBO) project. OBO’s goal is to create interoperable ontologies in the biological domain. Enables access to our data by other tools that are a part of the OBO Foundry

29. Lesson 2: Design for Change Need to design for change It’s the only thing that’s a given Projects should have the ability to evolve, discard and replace individual components with minimal impact on other pieces –Going from a stand alone 3-D Viz Tool to a browser based tool meant several changes for the branch –Moving to a Semantic Web version

30. Lesson 3: Community Building is hard A lot of excitement every time we pitch this to a group of researchers working on some species. But who will enter the data? 80/20 rule The system is only as good as what’s in it. Some sort of an incentive is needed to get new species started –Using NeuronBank wiki in classes –Then moving this data into NeuronBank

31. Lesson 4: Managing Humans Who owns this? –Code –Project/Sub-project Academic Attrition Publication potential to keep students interested –Ideally enough research for this to be the thesis/dissertation topic for a student
