gppi Connectivity

Hello Alfonso


The reuslts of  ROI to ROI gppi analysis, shows increased connectivity between ROI A AND ROI B. When I select ROI B that shows decreased connectivity between ROI B and ROI A for the same contrast. 


The analysis is done using bivarite regression.


Another region for a different contrast shows increased connectivity between ROI A AND ROI B. When I select ROI B that shows increased connectivity between ROI B to ROI A. 


 


My question is are these types of findings spurious connections? I was expectng correlational analysis to probably show bi-directional connectivity. Also opposing connectivity within same rois was also strange.
