We need a lot of data.
Because we are all so unique
Computers can store our data

We have algorithms

Neuroinformatics: A new discipline?
PhD student
Neuroinformatics reality:
A set of existing (distinct) disciplines?
Maybe neuroinformatics should be a web of disciplines?
create a web, not another mountain
The web, quite literally
me, a UWIN postdoc
Pediatric Mental Health
- Most mental health disorder are diagnosed at childhood and adolescence
-
How do brain tissue volumes change during development?
- are individual differences in development meaningful?
Healthy Brain Network
10,000 MRI scans
SO MUCH (statistical) POWER
a biobank from the Child Mind Institute
An MRI scan takes 5 min
Some kids can't stay still
Bad quality data
Bad inferences
Data needs visual inspection
10,000 MRI scans
Why not algorithms?
45 MPH
STOP!
we need some expertise
We should work together
Algorithms
- fast
- sometimes stupid
- needs lots of data to learn
Humans
- slow
- sometimes smart
- learns from sparse data

Need to "down-weight" some raters
| image id | rater 0 | rater 1 |
|---|---|---|
| 1 | 0 | 1 |
| 2 | 1 | - |
| Expert |

each rater is a feature
each image
is a sample

Thanks eLife Innovation!
oceanography/marine bio
How do brain tissue volumes change during development?
back to our question:
TL;DR
too long, didn't read in internet-speak
lets work together
to study the brain with Big Data
the web can break down barriers
between disciplines
Thanks to my Web Lab!
