Neurosciences Information Framework (NIF): An example of community Cyberinfrastructure for the Neurosciences Neurosciences Information Framework (NIF): An example of community Cyberinfrastructure for the Neurosciences Presentation Transcript

  • Maryann  E.    Martone,  Ph.  D.   University  of  California,  San  Diego  
  • “A  grand  challenge  in  neuroscience  is  to  elucidate  brain  func>on  in  rela>on  to   its  mul>ple  layers  of  organiza>on  that  operate  at  different  spa>al  and   temporal  scales.    Central  to  this  effort  is  tackling  “neural  choreography”  -­‐-­‐   the  integrated  func>oning  of  neurons  into  brain  circuits-­‐-­‐  Neural   choreography  cannot  be  understood  via  a  purely  reduc>onist  approach.   Rather,  it  entails  the  convergent  use  of  analy>cal  and  synthe>c  tools  to   gather,  analyze  and  mine  informa>on  from  each  level  of  analysis,  and   capture  the  emergence  of  new  layers  of  func>on  (or  dysfunc>on)  as  we   move  from  studying  genes  and  proteins,  to  cells,  circuits,  thought,  and   behavior....     However,  the  neuroscience  community  is  not  yet  fully  engaged  in  exploi;ng   the  rich  array  of  data  currently  available,  nor  is  it  adequately  poised  to   capitalize  on  the  forthcoming  data  explosion.    “   Akil  et  al.,  Science,  Feb  11,  2011  
  • •  In  that  same  issue  of  Science   –  Asked  peer  reviewers  from  last  year  about  the  availability  and  use  of   data   •  About  half  of  those  polled  store  their  data  only  in  their   laboratories—not  an  ideal  long-­‐term  solu>on.     •  Many  bemoaned  the  lack  of  common  metadata  and   archives  as  a  main  impediment  to  using  and  storing   data,  and  most  of  the  respondents  have  no  funding  to   support  archiving   •  And  even  where  accessible,  much  data  in  many  fields  is   too  poorly  organized  to  enable  it  to  be  efficiently  used.   “...it  is  a  growing  challenge  to  ensure  that  data  produced  during  the  course   of  reported  research  are  appropriately  described,  standardized,  archived,   and  available  to  all.”    Lead  Science  editorial,  2011   View slide
  • Neuroscience  is  unlikely  to  be   served  by  a  few  large  databases   like  the  genomics  and  proteomics   community  Whole  brain  data   (20  um   microscopic  MRI)   Mosiac  LM   images  (1  GB+)   Conven>onal  LM   images   Individual  cell   morphologies   EM  volumes  &   reconstruc>ons   Solved  molecular   structures   No  single  technology  serves  these  all   equally  well.    Mul6ple  data  types;    mul6ple   scales;    mul6ple  databases   View slide
  • hZp://neuinfo.org  
  • •  Current  web  is   designed  to  share   documents   – Documents  are   unstructured  data   •  Much  of  the   content  of  digital   resources  is  part  of   the  “hidden  web”   •  Wikipedia:    The  Deep  Web   (also  called  Deepnet,  the   invisible  Web,  DarkNet,   Undernet  or  the  hidden   Web)  refers  to   World  Wide  Web  content   that  is  not  part  of  the   Surface  Web,  which  is   indexed  by  standard   search  engines.  
  • •  NIF  has  developed  a   produc>on  technology   pla]orm  for  researchers  to:   –  Discover   –  Share   –  Analyze   –  Integrate     neuroscience-­‐relevant   informa>on   •  Since  2008,  NIF  has   assembled  the  largest   searchable  catalog  of   neuroscience  data  and   resources  on  the  web   •  Cost-­‐effec>ve  and   innova>ve  strategy  for   managing  data  assets   “This  unique  data  depository  serves  as  a  model   for  other  Web  sites  to  provide  research  data.  “  -­‐   Choice  Reviews  Online   NIF  is  poised  to  capitalize  on  the  new  tools   and  emphasis  on  big  data  and  open   science
