Dear Klaas and DCMers,
I used the DCM to provide an insight into connectivities among some
interesting regions. The modulatory effects of two conditions were described
in the attached picture. A solid lines indicated the modulatory effect on
the connection was significant, whereas a dotted line indicated the
modulatory effect on the connection wasn't significant (according to one
sample t test). Figures gave out parameters of modulatory effects.
According to my coarse interpretation, the modulatory effect of
condition one (above) reduces the connectivity among three regions compared
to the intrinsic connectivity, whereas the modulatory effect of condition
two (below) retains the connectivity among three regions.
I am not confident in my interpretation. Because papers I read before
always reported positive parameters. However, my results included many
negative parameters and non-significant parameters. Does that mean my
results are very bad? Is there any means of redress?
Best Wishes!
