Hi Adam, sorry for the delay in my answer

The aparc.a2009s is based on the anatomical rules we published in Neuroimage in 2010: - There are 2 separate labels : one is sulcal, for the posterior part of the lateral fissure (Lat_Fis-post), the other one is gyral, for the planum temporale (G_temp_sup-Plan_tempo) - I’m not quite sure to understand the second part of the question : in my mind the lateral fissure can be divided in 3 segments (anterior, middle, posterior), and the posterior one is more or less ascending. There was only a single label (Lat_Fis-post) for the posterior segment of the lateral fissure

I hope it helps — Christophe Destrieux, Unité « Imagerie et Cerveau » UMRS INSERM U930, Université François Rabelais de Tours Service de Neurochirurgie Laboratoire d’Anatomie, Faculté de Médecine, 10 Bd Tonnellé - 37032 Tours - France Bureau: +33 2 47 36 61 36 | Fax +33 2 47 36 62 07 | Mel Bureau: christophe.destrieux@univ-tours.fr Web : http://www.u930.tours.inserm.fr/ http://www.u930.tours.inserm.fr/

Hello,

I checked the listserv history, but couldn't find an answer to my question:

With the 2009 parcellation scheme, 1) does the planum temporale parcellation include the posterior ascending ramus (which Destrieux et al. 2010 seems to imply) and 2) does the planum temporale include the posterior descending ramus?

Thank you!
