[caret-users] Question about paint regions modalities?

[John Harwell]

Hi Antoine,

If you have paint selected as an overlay with modalities as the  
selected paint column and press the "?" button, comment information is  
displayed.  For the modalities, the comment is:

Cleaned up Right modalities (language, gustatory, olfactory) 27 Aug 2006
Motor revised; cognitive, emotion_limbic added (DVE 13 Aug 2006)
Visual (blue), auditory (red), somatosensory (green),
motor (purple), olfactory (brown). From:
Van Essen, D.C. (2002) Organization of visual areas in macaque and
human cerebral cortex. In: The Visual Neurosciences.
L. Chalupa and J.S. Werner, MIT Press (in press)

A preprint of the referenced article is available at "http://brainmap.wustl.edu/resources/VisChapter.pdf 
".

Also in the PALS atlas is an areal estimation file with a modalities  
column.  This is similar to a paint file, however, the boundaries  
between regions are "fuzzy" to indicate the boundaries are estimated  
and not exact.

My suggestion is that you read the referenced article prior to using  
the modalities as an ROI.  I expect that Dr. Van Essen will reply at  
some time with his opinion.
