Hello Doug,
thank you very much for your answer. But how I can find which other areas the cluster  overlaps, since QDEC only gives the name of the parcel that contains the max point?
Is there any other (semi)automated way of obtaining the names of the other structures that the cluster contains (either in whole or parts of)?
Or is it just down to one's own knowledge of brain anatomy?

I would definitely show a picture of it, say which areas it overlaps,
and spec the coordinates for the max (which is what QDEC reports).
