This methods study benchmarks common effective connectivity metrics on simulated time-delayed networks and finds multivariate transfer entropy most accurate but computationally intensive, while zero-lag metrics fail for time-lagged interactions and simpler metrics (Granger causality, mutual…
Reliable EC metric selection for noisy, sparsely sampled human electrophysiology improves reconstruction of directed brain networks, which is a necessary step toward robust electrophysiology-based biomarkers and circuit-targeted therapies (e.g., DBS optimization) in Parkinson's disease.
