Hi all,
I have two scenarios from some DCM analyses that I would like to get suggestions/thoughts on
how to interpret...all help appreciated!!!
1. Signficant modulatory (bilinear) effects on a pathway with non-significant intrinsic connectivity.
Can one interpret the modulatory effects as activating a pathway, or does intrinsic connectivity
have to be also significant to do so?
2. Say the bilinear effect is positive and significant and the intrinsic connectivity is negative and
non-significant. Does that mean an "inhibitory" pathway is activated, or because the intrinsic
connectivity is non-significant, that the pathway is activated but of unkonwn excitatory vs
inhibitory nature?
2. What if the bilinear effect is positive and significant and the intrinsic connectivity is negative
and significant, can one argue that an "inhibitory" pathway has therefore been activated?
much, much thanks!
Amit
