I was wondering whether a D matrix could be coputed in a spectral DCM analysis; more specifically, I would like to have something like in Figure 3 of this paper:
Chand, G. B., Hajjar, I., & Qiu, D. (2018). Disrupted interactions among the hippocampal, dorsal attention, and central-executive networks in amnestic mild cognitive impairment. Human Brain Mapping, 39(12), 4987–4997. http://doi.org/10.1002/hbm.24339
namely to determine the modulatory inputs of one node onto the connections between two other nodes.
