Topic: exogenous contributions

In the past decades, functional MRI research has investigated task processing in largely static fashion based on evoked responses during blocked and event-related designs. Despite some progress in naturalistic designs, our understanding of threat processing remains largely limited to those obtained with standard paradigms with limited dynamics. In the present work, we applied Switching Linear Dynamical Systems (SLDS), a framework that estimates a generative model of the data with both states and transitions like HMMs, to uncover the dynamics of threat processing during a continuous threat-of-s
