“An unaided human’s ability to process
large data sets is comparable to a dog’s
ability to do arithmetic, and not much more
valuable.” –Michael Nielson, Reinventing

• NIF’s mission is to maximize the awareness of, access to and
utility of digital resources produced worldwide to enable better
science and promote efficient use
– NIF unites neuroscience information without respect to domain, funding
agency, institute or community
– NIF is a library for scholarly output that is a web enabled resource and
not a paper
– Aggregates all the different databases, tools and resources now
produced by the scientific community
– Makes them searchable from a single interface
– A practical approach to the data deluge
– Educate neuroscientists and students about effective data sharing

13. What about my data?
•Best practice:
•Put it in a repository
•What repository?
•Community
repository for your
data type, e.g., GEO
•General repository:
•Dryad
•FigShare
•Institutional repository
•Research libraries are
setting up repositories
to manage their
“digital assets”

14. Requirements for effective
data sharing • Discoverability
– Data can be found
• Accessibility
– Data can be accessed and
access rights are clear
– Links to data are stable
• Assessability
– The reliability of the data can
be determined
• Understandability
– The data can be understood
• Usability
– The data are in a usable form
• Publishing data on your
website or as
supplemental material is
not the best way to make
it available

• 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.
16. WWhhaatt ddoo yyoouu mmeeaann bbyy ddaattaa??
Databases come in many shapes and sizes
• Primary data:
– Data available for reanalysis, e.g.,
microarray data sets from GEO;
brain images from XNAT;
microscopic images (CCDB/CIL)
• Secondary data
– Data features extracted through
data processing and sometimes
normalization, e.g, brain structure
volumes (IBVD), gene expression
levels (Allen Brain Atlas); brain
connectivity statements (BAMS)
• Tertiary data
– Claims and assertions about the
meaning of data
• E.g., gene
upregulation/downregulation,
brain activation as a function
of task
• Registries:
– Metadata
– Pointers to data sets or
materials stored elsewhere
• Data aggregators
– Aggregate data of the same
type from multiple sources,
e.g., Cell Image Library
,SUMSdb, Brede
• Single source
– Data acquired within a single
context , e.g., Allen Brain Atlas

23. Current challenge: With so much
available, how do I find what I need?
• “What genes are upregulated
by chronic morphine?”
– It depends
• Most often use cases require
connecting a researcher to
relevant data sets and
appropriate tools
– Depending upon the data and
tools, the answers may differ
• Many databases have tool
bases and workflows that
they support

• Gemma: Gene ID + Gene Symbol
• DRG: Gene name + Probe ID
• Gemma presented results relative to baseline chronic
morphine; DRG with respect to saline, so direction of change is
opposite in the 2 databases
• Analysis:
•1370 statements from Gemma regarding gene expression as a function of chronic
morphine
•617 were consistent with DRG; over half of the claims of the paper were not
confirmed in this analysis
•Results for 1 gene were opposite in DRG and Gemma
•45 did not have enough information provided in the paper to make a judgment

27. 3. SciCrunch: A social network for
data and tools
• NIF platform has been adapted to
create SciCrunch
– Beta release: http://scicrunch.com
• Create more narrow community-based
portals based on common
data platform
• Select your data; organize it as you
wish
• Cost effective: a data portal can be
set up in a few hours
• Connects communities through data
and tools
• Shared curation-shared knowledge

46. The tale of the tail
“Human neuroimaging typically is performed on a whole brain basis.
However, for several reasons tail of the caudate activity can easily be missed.
•One reason is limitations in the normalization algorithms, that typically are
optimized to maximize accuracy for cortical rather than subcortical
structures. ...
•A second reason is that standard neuroimaging atlases such as the Harvard-
Oxford structural atlas used with neuroimaging analysis programs such as
FreeSurfer truncate the caudate at the body, and completely exclude the
tail...
•A final reason is that the tail of the caudate is close to the hippocampus,
and could be misidentified as such especially in tasks involving learning and
memory.
Therefore, the tail of the caudate may be recruited in additional cognitive
tasks, but yet not have been properly identified and reported in the
neuroimaging literature”

– Many data
• Generation of data is getting easier shared data
• Data space is getting richer: more –omes everyday
• But...compared to the biological space, still sparse
– Many eyes
• Wisdom of crowds
• More than one way to interpret data
– Many algorithms
• Not a single way to analyze data
– Many analytics
• “Signatures” in data may not be directly related to the question for which they
were acquired but tell us something really interesting

Current model: Scholars are producing multiple types of research objects; each goes to their own infrastructure with little coordination among them.
Consumer no longer exclusively a scholar: General public wants access to what they pay for; automated agents are accessing first and mining the content.
