A state-space model for dynamic functional connectivity.Dynamic functional connectivity (DFC) analysis involves measuring correlated neural activity over time across multiple brain regions. 
state-space model
To address this issue, we propose a multivariate stochastic volatility model for estimating DFC inspired by recent work in econometrics research.

Using this statistical model within a sequential Bayesian estimation framework, we use blood oxygenation level dependent activity from multiple brain regions to estimate posterior distributions on the correlation trajectory.
