Sample characteristics and use of the IIT Human Brain Atlas (v.5.0)
Hello,
Thanks for the great work. I have 2 questions before we use the IIT atlas:

1) I was wondering what were the characteristics of the subjects used for v5.0 of the atlas? Is it the sample of 72 healthy young and middle-aged adults (22 male, 31+-> 13 years of age, 18–59 years of age) from the Enhanced Nathan Kline Institute Rockland Sample referred to in the Zhang & Arfanakis (2018) Neuroimage paper ?

2) We are planning on using your connectivity matrix from the DK atlas (IIT_connectivity_matrix.txt). I was expecting higher connectivity between the same regions in the left and right hemispheres. Since I am not in the connectivity field, I was wondering whether it is ok to use this connectivity matrix as a measure of axonal strength between each DK region, even for the same region in both hemisphere.

Thank you.
Regards
Olivier
