yes, the methods were described in that paper, and a more recent one by Rahul Desikan (which should be on our wiki). Not sure about the comparison of the methods though. Bruce On Thu, 28 Aug 2008, bin.lv wrote:

Hi Bruce,

Are this labeling techniques described in "Automatically Parcellating the Human Cerebral Cortex" (Fischl B. et al,Cerebral Cortex,2004)? I read a paper "Local landmark-based mapping of human auditory cortex"(Xiaojian Kang et al,NeuroImage,2004).They marked the five anatomical landmarks on the flatten surface, to identify the auditory cortex. Do these two methods get the similiar results?

Hi Bin, we do label Heschl's gyrus in the ?h.aparc.annot parcellation, so you could use it as a proxy for primary auditory cortex. Sorry, we haven't gotten any histology in those regions yet. cheers, Bruce On Wed, 27 Aug 2008, bin.lv wrote:

Hi all,

After getting the cortical surface with Freesurfer,could I identify the location of the auditory cortex in each individual, and further then calculate the surface area , or the volume of it? In the paper of Cerebral Cortex " Cortical Folding Patterns and Predicting Cytoarchitecture", it seems that there is no auditory cortex yet.

Thanks in advance, Bin Lv

Hi Padraig,

This cytoarchitectonic map is a probabilisitc map, it's maybe useful for the anatomical interpretation of functional activation in fMRI study, I guess. But I'm not sure if it can be used for comparing the structual difference in auditory cortex between two groups. Could you tell me any example of such application?

Best wishes!

You may find the following cytoarchitectonic maps helpful in localising primary auditory cortex: http://www.bic.mni.mcgill.ca/cytoarchitectonics/ Padraig bin.lv wrote:
