Estimation of Directed Effective Connectivity from fMRI Functional Connectivity Hints at Asymmetries of Cortical Connectome

Interpretation of estimated cortical interactions and intrinsic noise.
A Weak match between EC and SC values. Each red cross corresponds to a connection. B Plot of the sum of incoming C weights versus the sum of outgoing C weights (x-axis and y-axis, resp.) for each cortical area (red cross). C 3D mapped representations on the cortex of the variances of the empirical BOLD signal, sums of incoming weights in EC, and intrinsic noise (related to spontaneous noisy activity). Red corresponds to larger values and blue to small values.
