English nomenclature

[MSh]

Hi everyone

I am trying to match Brainvisa sulci labelling with atlas, however for some sulcal parts the equivalence between the lables in french and english seems quite tricky. Does any one have a similar experience and possible solutions for this?

Many thanks

Hi,
Actually, Matthieu Perrot has done so for the nomenclature used for the new learning database, and has also made a probabilistic atlas from the SPAM model. You can find this on our lab website:

Hi Denis

This is certainly helpful but still not exactly the same as the nomenclature used in Ono's atlas. For example what is considered to be post-central sulcus in Ono's atlas seems to be shared between post-central and intraparietal sulci with Brainvisa nomenclature. There are actually many mismatch between Brainvisa and Ono's nomenclature and I was wondering if there's a well established correspondence between the two so that personal interpretation could be avoided.

Thanks

I am afraid you have to make up your mind yourself about these disagreements. The point is that very few people
really worked on this topic, and each of them used unclear definitions. The fact that we based our point of view on the
sulcal root theory of Jean Regis led us to develop a specific nomenclature (see is paper from 2005 for instance when interpreting
Matthieu Perrot's nomenclature) to deal as we could with sulci interruptions. The consequence is that there is no perfect match with Ono's nomenclature.
The notion of postcentral sulcus you suggest is very fuzzy in fact, except if you just draw manually a line parallel
to the central sulcus more or less following the underlying folds, but this is not the kind of approach we have,
we stick to a data driven bottom up point of view.
