Hi Lena

Here is the link to the HBM 2009 poster : http://www.nmr.mgh.harvard.edu/martinos/publications/posters/HBM-2009/HBM09-...

Following is the "insula" section of the paper we are going to publish "On the inflated view, the insula was clearly limited by the circular sulcus of the insula divided in 3 segments: superior [S_circular_insula_sup, 49], horizontally limiting the insula from the subcentral and inferior frontal gyri, anterior [S_circular_insula_ant, 47], vertically limiting the insula from the orbital gyri, and inferior [S_circular_insula_inf, 48], obliquely limiting the insula from the superior aspect of the superior temporal gyrus. The lateral sulcus or fissure results from the juxtaposition of fronto-parietal and temporal opercula, and is classically divided in anterior, middle and posterior segments (Duvernoy et al., 1991). The superior and anterior segments of the circular sulcus of the insula anteriorly fused to form the anterior segment of lateral sulcus that rapidly splits into vertical [Lat_Fis-ant-Vertical, 40] and horizontal rami [Lat_Fis-ant-Horizont, 39]. Since the inflated representation widely separated the opercula bordering the insula, the middle segment of the lateral sulcus was missing on inflated reconstruction. Finally, the superior and inferior segments of the circular sulcus of the insula posteriorly merged to become the posterior segment of the lateral sulcus [Lat_Fis-post, 41], which curved superiorly to enter the inferior parietal lobule.

The central sulcus of the insula ran antero-inferiorly from the superior segment of the circular segment of the insula. It was a small sulcus that was not always visible on its whole course on the inflated views. It divided the insula in two parts: the short insular gyri [G_insular_short, 18] (anterior) and the long insular gyrus (posterior). Due to their small size, the central sulcus of the insula and the long insular gyri were grouped in the same label [G_Ins_lg_and_S_cent_ins, 17]."

I hope that it helped

cheers

Is there any reference available for tracking the boundaries of 5 parcellations within insula as given by Destrieux a2009s?
