Dear Dr. Buechel,
If you remember from our previous correspondence , I have been using your
learning study model for our fMRI paradigm here. I am very keen to work on
the effective connectivity analysis that you have done in your paper but
using DCM.
As far as I gather , DCM required an external input ( in this case it
would be the encoding block??) which will modulate the V1 area.
I will enter the model that you have mentioned in your paper (Predictive
value of Changes in effective Connectivity for human learning).
Do you advise that this would be feasible for such a design to do DCM on?
Is it necessary for DCM modelling to have a 2x2 factorial design , like
the one for the attention study?
In DCM, I guess it would not be possible to enter the Early vs Late Block
you modelled for SEM.
I would just like to observe the weight of coonection between the encdoing
network.
Look forward to hearing from you.
With best regards,
Saugy
