Hi Meike
sorry for the delayed response. For the ventricular stuff you are probably
better off contacting the CMA (Dave Kennedy, Nikos Makris, Verne Caviness).
The inf-lat-vent is the part of the ventricle in the medial temporal lobe
(the temporal horn), but they could provide a more exact description.
For the cc divisions, we split it up into fix equal length segments along
its primary eigenaxis. This is arbitrary and you could change it by
changing the way mri_cc is called.
cheers
