Hi Woogul,

If I understand correctly, you are looking for a way to say that LSTG responds after RSTG during the 'previously won' condition.
While the ROI averages hint that there **may** be a delay difference, it is a stretch to state that the delay difference reflects neuronal delays. It is quite possible that the delay differences reflect vascular differences between these areas.
You might start to have a story however, if you have a task that activates these same regions but without the delay difference or with a difference in the opposite direction.
How you estimate delay differences is another topic that requires more reflection on your experiment and your data processing. But I would not embark on this until you are sure that these differences are not of vascular origins.

cheers,
ziad
