Hi Freesurfer experts,
I would like to know what are the equivalent labels to
- Gyrus Intralmibic - Sulcus semmi annularis
In the label file FreeSurferColorLUT.txt. I have checked the paper "Automatic parcellation of human cortical gyri and sulci using standard anatomical nomenclature" but the information there is not useful (e.g. indusium griseum does not appear in that file).
Thanks and best regards.
Fidel.
Hi Fidel
as stated in the paper you cited, the intralimbic gyrus is made of : prehippocampal rudiment, indusium griseum and hippocampus. Only the latter vas clearly visible on the MR scans used to build the atlas, but was not correctly unfolded. For this reason the intralimbic gyrus can not be automatically labelled on the surface. Nevertheless, Hippocampus is segmented by the volume autoparcellation.
Similarly, Sulcus semi annularis was not correctly unfolded and was not labelled.
Sorry about that
Hi mr Destrieux,
Does this mean that those structures cannot be found in ANY segmentation or labelling made by freesurfer?
Thanks again for your quick answer,
Fidel.

not that I know, except for hippocampus which is available on the volume segmentation
Bruce : am I right?
cheers
I meant : am i right to think that we don't have any other parcellation available showing the other labels Fidel would like to use ? (I thought that maybe somebody localized these structures in a way similar to what you did for the entorhinal cortex in your exvivo/invivo 2008 paper)
cheers
no we haven't done them On Wed, 12 Jan 2011, Christophe Destrieux wrote:

Thanks to both of you.
Cheers.
