DTI-Circuit Requirements

Functional Connectivity (Schnitzer Group) Requirements

We made some progress in the fall on an interactive visualization that overlays a node-link diagram of functional brain connections above a anatomical map of these regions. For a starting point, this was in 2D (i.e., the spatial layout of the nodes was simply mapped over a single, static, sagittal view of the brain). In our talks with the Stanford group, it seems they are ultimately looking for a 3D "database" of these connections. In other words, they want to view connections in the context of the full brain volume.

A demo video of that tool is available here [ Media:Steve_2dcircuit_prototype.mp4 ]. Jeff Law, who was/is a post-doc in that group, hints at some reqs for the next design in his feedback to that video:

"The movie looks REALLY COOL. And a working version of this would be very helpful for us! But just to clarify what you've done:

So you basically loaded the database from the Allen atlas (the pdf file) and combined it with the connectivity information you got from BAMS. Am I right? One thing that would be really nice is instead of searching for specific area and show the connections (which is very useful), the software let the user to choose the area of interest by moving the cursor (and the tag would show the name of the area), and the connections to/from that area would be shown interactively. Do you get what I mean?"
