New ISCL Framework Infers Signed Brain Connectivity Dynamics

By PulseAugur Editorial · [1 sources] ·

Researchers have developed ISCL, a novel framework utilizing latent stochastic differential equations to infer dynamic effective connectivity (dEC) in the brain. This method addresses limitations in existing dEC approaches by providing a causal rationality guarantee and identifiability analysis, allowing for the distinction between excitatory and inhibitory influences. ISCL demonstrated strong performance on synthetic benchmarks, accurately recovering causal structures and distinguishing influence types. When applied to fMRI data from the HCP Social Cognition task, ISCL revealed a stable signed architecture, identified key networks involved in social cognition, and highlighted strengthened causal outflow from the default-mode and frontoparietal networks during theory-of-mind processing.

    Identifiable Signed Causal Learning via Latent Stochastic Differential Equations for Inferring Brain Dynamic Effective Connectivity

    Understanding how brain regions interact to support cognitive tasks requires characterizing directed causal influences among them, known as effective connectivity (EC). As inter-regional coupling changes over time, a dynamic EC (dEC) estimate is required to track this temporal va…
