Excitation vs. Inhibition
Dear Dr. McLaren,
I have a question regarding the interpretation of PPI results. Could enhanced coupling for experimental condition 1 vs. 2 between seed region A and a different region B reflect increased inhibition of region A by region B (or vice versa), or can it only reflect increased excitation?
Specifically, based on the results of a PPI analysis showing enhanced coupling between seed region A and another region B for condition 1 > 2, I performed a DCM analysis which showed that during condition 1, region B's influence on region A is strongly decreased, becoming negative/inhibitory. Are these results plausible?
Thanks a lot in advance and all the best,
Phil
