Table 4.

Task invariant (A-matrix) coupling parameters in 1/s of the averaged DCMs (P < .05, Bonferroni corrected) within each group and differences in endogenous connectivity parameters between patients and controls (P < .05, Bonferroni corrected separated by matrices). The difference contrast was defined as parameter_HC–parameter_WC. A significant t-value greater than zero indicates a less strong influence of the connection in the patients' model. A significant t-value smaller than zero indicates a stronger influence of the connection in the patients' model.
