Dear all,
in a fast event-related design I defined two seed regions for their significant activity during two different stages of a series of trials (e.g. a preparatory phase and the outcome of a given action).
Now, I was wondering whether I can obtain a measure of functional connectivity for these seeds during the two events of interest.
Since this is a fast-event related design, the two events are separated by ~2.5 sec (with some random jittering).
Am I allowed to run a beta-series correlation between each seed and the rest of the brain during the two relevant phases of each trial?
Should I consider PPI?
Thanks for your help,
Best
D
