Hello,

Do physiological varibales need to be measured/controlled when doing a context-dependent connectivity analyes?

It would seem that any spurious correlations due to physiololgy would not be different for condition A compared to condition B (unless of course, condition B is much scarier than condition A). So a test of connectivity associated with conedition A versus B would not reveal any differences due only to physiology.

Is this reasoning correct?

If so, why do people report covarying out physiological noise from correlational analyses when comparing 2 conditions? Does it matter whether the conditions were acquired in different scanning sessions?
