Research Challenge Understanding the brain is the greatest informatics challenge • Enormous implications for science: • medicine • biology • computer science
Collecting the Evidence • 100,000 neuroscientists are • generating vast amounts of data • molecular (genomic/proteomic) • neurophysiological (time-series electrical measures of activity) • anatomical (spatial) • behavioural
Current Problems in Neuroinformatics • Data is: • expensive to collect but rarely shared • proprietary and locally described • The result: • a shortage of analysis techniques that can be applied across neuronal systems • Limited interaction between research centres with complementary expertise
CARMEN CARMEN uses e-science to tackle the problem CARMEN supports the archiving, sharing, discovery, integration and analysis of neuroscience data EPSRC e-Science Pilot Project (2006-10) Builds on previous e-science projects DAME, Gold, myGrid, BROADEN, CISBAN...
CARMEN focuses on Neural Activity • raw voltage signal data is collected using single or multi-electrode array recording neurone 1 neurone 2 neurone 3 cracking the neural code
CARMEN : A Hub & Spoke Structure • Hub: A “CAIRN” repository for the storage and analysis of neuroscience data • Spokes: Neuroscience projects that produce data and analysis • services for the hub, and use it to address key • neuroscience questions WP1 Spike Detection & Sorting WP2 Information TheoreticAnalysis of Derived Signals WP 3 Data-Driven Parameter Determination in Conductance-Based Models Data Storage & Analysis WP5 Measurement and Visualisation of Spike Synchronisation WP6 Multilevel Analysis and Modelling in Networks WP4 Intelligent Database Querying

Data Collection from a Multi-Electrode Array Data Visualisation and Exploration Spike Detection Spike Sorting Analysis Visualisation of Analysis Results Currently, this is a semi-manual process CARMEN has automated this…. A Typical CARMEN Scenario

Dynamic service deployment A request to s4 cannot be satisfied by an existing deployment of the service R The deployed service remains in place and can be re-used - unlike job scheduling
Routing to an Existing Service Deployment A request for s2 is routed to an existing deployment of the service
Support for sharing vast amounts of data: How was this data produced? Which workflow produced this data? Is there any data of this type…..? Are there services that process this data? e-Science Challenges: Discovery & Interpretation
Extensible, standardised metadata for neuroscience data formats (e.g. timing, data channels) experimental design (e.g. stimuli or drug treatments) concurrent data (e.g. behaviour, physiological measures) experimental idiosyncrasies (e.g. artifacts) experimental conditions (e.g. animals, temperature) e-Science Challenge: Metadata Design
How to locate patterns in time-series data across multiple levels of abstraction Challenge: Discovery
“Only I am allowed to see this data” “My collaborators can look at this data” “Anyone can see this data” “The funders want the data to be openly available after 1 year” The Gold Project’s Security infrastructure will be used for this Challenge: Controlling Sharing
Reproducible e-Science curating services as well as data repositories of deployable services dynamic service deployment Challenge: Reproducible e-Science
CARMEN CARMEN is delivering an e-Science infrastructure that can be applied across a range of diverse and challenging applications (not only neuroscience) CARMEN enables cooperation and interdisciplinary working in ways currently not possible CARMEN will deliver new results in neuroscience, computer science and medicine Demos on North East Regional e-Science Centre, White Rose and EPSRC stalls
