'find_peaks', I believe, will do the job that you want. Except for the 
Brodmann area part, which is next to impossible since we don't have 
real maps of most Brodmann Areas.

That would be a rather long list of numbers for a boundary, would it 
not? I'm not quite sure I understand what you are after.

You could get the tag file produced by find_peaks and look at it in 
register together with a probability map generated for a certain area, 
or, alternately, the map of structures used by ANIMAL to do its 
segmentation to get some idea about the area each peak is in.

The combination of tag files of peaks together with anatomical data and 
structural probability maps does the job pretty well for me anyways.
