Expected posterior parameters (posterior probabilities in brackets) for the A matrix parameters (intrinsic and extrinsic fixed connections) and the B matrix parameters (modulation of connections); sample of n = 52 human participants. The matrix is organized such that the origin of connections is represented by the columns, and the target of connections is represented by the lines.
aST anterior superior temporal cortex, mST mid superior temporal cortex, pST posterior superior temporal cortex, pSTS posterior superior temporal sulcus, HG Heschl’s gyrus.
