I have two questions related to aparc.a2009s+aseg.mgz:

1. I was wondering if there is a mapping between structures in aparc+aseg.mgz & aparc.a2009s+aseg.mgz ? For example I would like to know what "isthmuscingulate" in aparc+aseg maps to in aparc.a2009s+aseg.mgz.

2. I could find a lobe mapping for aparc+aseg.mgz here:

Is there a similar lobe mapping for aparc.a2009s+aseg.mgz ? 

Thanks
