Dear all,
I´m relatively new to CONN and got stuck with two questions:
1) I am using the ROIs from the default atlas file (FSL Harvard-Oxford). Given that the ROIs are split in left and right, if I for instance aim to test bilateral amygdala-hippocampus connectivity, how shall I proceed? If amygdala is my source, as far I as understood, I can select both left and right amygdala and set the contrast to (0.5 0.5]. But what about my target ROI, how do I specifiy that I want both left and right hippocampus?
2) Is it feasible to do network connectivity analyses between salience network and default mode network by combining respective regions into one ROI? So my seed regions would be all salience network regions, and target would be all DMN regions. For the target I guess I could specify my contrast accordingly, but again I have troubles understanding how I would specify that I want to have a "combined" target region.
If someone has any ideas on this, I´d be very glad to hear them :)
Thanks in advance!
Cheers,
Laila
