Degree Centrality Equation

Submitted by syang on Wed, 11/16/2016 - 22:27

Hi. Dr. Chao-Gan Yan

I am Seungnam 

I am analyzing the rFMRI data using DPARSFA progrm. Thank you for good program.

I am using the subfunction of Functioanl connectivity and Degree Centrality of DPARSFA.

I understand that Degree Centrality means functional connectivity strength, that is global functional connectivity density. Am I right?

How do you calculate the Degree Centrality?

Could I know the equation of Degree Centrality and it's reference?

I already had a Buckner et al. 2009 and Zuo et al. 2012. But still not clear the concept.

If you let me know the equation of Degree Centrality, it might be a great help to understand the concept. 

Again, Thank you for your good program

 

Best, 

Seungnam

Hi, Seungnam Yang

I think you can find more details about degree centrality in the courses uploaded no the rfmri.org

For a given voxel:

1. Calculate the functional connectivity map;

2. Threshold (e.g., r=0.25)

3. Sum.
