Terry (et al.),
Although the ECHDB is evidently defunct, the data sets you are
interested in (plus much more) are available by alternate routes.
The primary data sets are accessible at a website at the Zilles lab
(and also one at McGill) that is indicated lower down in this
message. In addition, we have mapped all of their published data
sets to our new PALS human atlas (Van Essen, 2005, Neuroimage; see
link below), where they can be viewed as volumes and after mapping to
the atlas surface.
I will take the liberty of showing you how I dug it out from the PALS
atlas in SumsDB and how you can easily navigate a similar trajectory.
Link to our SumsDB database (http://sumsdb.wustl.edu/sums/)
Click on the Human PALS atlas image set, which will launch a WebCaret
window. In a moment, this will bring up an individual human
hemisphere surface (scene 1).
For your purposes, you want scene 14, which includes a probabilistic
map of area 45 from Amunts et al. (2004). I have a screen capture
that illustrates this, but I will email it to you separately so that
this email doesn't get bounced because of its size.
To get to areas 1 - 3, there are no pre-computed scenes listed, so
press the D/C button, which will bring up the Display Control window.
From the metric column pulldown menu, select 'Brodmann_3a....'.
Your WebCaret and Display Control windows should look as in the
figure that will be emailed separately.
Click on the '?' button next to the metric 'Brodmann_3a...'
This will bring up a comment window that includes the following links
to the Zilles et al primary data.

Once you're in SumsDB and viewing atlases via WebCaret, there's lots
of other data that you might find of interest.

Hi Donna,
Sorry, I misspelled the acronym for the database. It is ECHDB
(European Computerized Human Brain Database) rather than ECHBD.
The original reference I found was in Geyer et al. (2000) "Areas
3a, 3b and 1 of human somatosensory cortex. 2. Spatial
normalization to standard anatomical space" NeuroImage 11:
684-696. In that paper Geyer et al. reference an article by Roland
et al. (2000) entitled "ECHDB, a database for functional-structural
and functional-functional relations to neuroimaging", NeuroImage
9S: 128. The website at that time was: http://fornix.neuro.ki.se/
ECHBD/Database/, but this is now defunct. I was hoping to obtain
images of the population maps that Geyer et al. (1997, 1999, 2000
and 2001) made for the components of SI, which Geyer et al. (2000)
stated were available through the database.
