Note: Significant modulatory parameters (‘B-matrix’, α ≤0.01) of connectivity between subregions. Based on a random effects permutation test for the null hypothesis ‘no parameter difference between tasks’. The strength is given as posterior expectation from the optimum Bayesian parameter average model.
