DMN/SN/FrontoParietal Seed Info

Hi there,


 


I was curious if there was some form of repository with information regarding the voxel selection for the ROIs.

My seed-to-voxel analysis identified a significant cluster using the Lateral Parietal (DMN) seed. The lateral parietal cortex is a large surface, and I don't know what cortical regions might be incorporated into the seed—the angular gyrus or perhaps the lateral occipital, for example. I did find the networks.txt file (~/conn/rois), which informed me that the LP (L) is MNI -39, -77, 33, which are informative as center coordinates (is this correct?), but wondering if there was any other information beyond this. Loading the .nii files into FSLeyes is okay for visual inspection, but not particularly helpful for knowing the dimensions. 

I'm essentially just trying to have the most specific information possible when reporting results, as my inferences might change depending on the scope of the seeds.

Warm regards,


Olivier
