Effective connectivity within the auditory feedback control network. Structural equation modeling demonstrated significant modulation of interregional interactions within the schematized network when auditory feedback was perturbed during speech production. Pair-wise comparisons of path coefficients in the normal and perturbed feedback conditions revealed significant increases in the positive weights from left posterior superior temporal gyrus (pSTg) to right pSTg (the path labeled a in the diagram above), from left pSTg to right ventral premotor cortex (PMC; path b), and from right pSTg to right inferior frontal gyrus, pars triangularis (path c) when auditory feedback was perturbed during speech production. Additional abbreviation: MC = motor cortex.
