Coordinates of brain regions
Bryan Bishop
I am looking for a dataset that maps different brain regions to
different bounding boxes, or even different fuzzy coordinates within
the brain. Anything more particular would be greatly appreciated as
well.
There seem to be a few coordinate systems already out there such as:
Talairach, MNI, stereotaxic, and spherical systems. Yet, I still can't
find any models that say "here is an example of a standard model of a
brain, and here is a list of bounding geometries that correlate to
different names of regions."
For others looking for similar information, the Allen Brain Institute
dataset of gene expression mapped to different tissue slices is
awesome. Though it's not quite what I'm looking for here.
Thank you,

I once got some fMRI data from a research group at the University of
Buenos Aires. The data consisted of measurements from several
individuals but the measurements had already been rescaled to some
"standardized" brain consisting of 216,464 so-called "voxels" (cubic
pixels). I'm not certain of what standardization procedure was
utilized.
I have the list of rectangular coordinates in 3-space of each of the
216,464 voxels and I'd be happy to email it to you. It's not a
mapping but it's the territory to be mapped, at least. I'll also send
you the name and email address of the researchers I worked with
originally so you can get more information.

I'd like that very much, yes, thank you. Is this by any chance
volumetric based morphometry / spm? Since I began my search I only
found ICBM and one other list of regions, but these are just lists and
somehow mapped to giant dot img files (making it rather useless). I am
fairly certain that there are more than 57 regions in the human brain.
