Sparse Estimation of Resting-State Effective Connectivity From fMRI Cross-Spectra
In functional magnetic resonance imaging (fMRI), functional connectivity is conventionally characterized by correlations between fMRI time series, which are intrinsically undirected measures of connectivity. Yet, some information about the directionality of network connections can nevertheless be ex...
