DCM experts,
I have a question about SNR differences within a single network, which,
to my knowledge, hasn't been addressed on the listserv or in any
publications. In the network I am considering, the regions are
considerably different in size. As a result, the number of active
voxels to extract activation from differs significantly across regions
and this will introduce variability in SNR for the different
timeseries. Will this have a detrimental effect on DCM estimation?
Thank you,
Ian
