Recent studies have proposed that one can summarize brain activity into dynamics among a relatively small number of hidden states and that such an approach is a promising tool for revealing brain function. Hidden Markov models (HMMs) are a prevalent approach to inferring such neural dynamics among discrete brain states. However, the impact of assuming Markovian structure in neural time series data has not been sufficiently examined. Here, to address this situation and examine the performance of…

Causal roles of prefrontal cortex during spontaneous perceptual switching are determined by brain state dynamics
It is revealed that the brain-dynamics-dependent behavioural causality is underpinned by transient changes in the brain state dynamics, and such neural changes are determined by structural transformations of hypothetical energy landscapes.


Brain network dynamics in schizophrenia: Reduced dynamism of the default mode network
Severity of positive symptoms was associated with a longer proportion of time spent in states characterized by inactive default mode and executive networks, together with heightened activity in sensory networks, and classifiers trained on the state descriptors predicted individual diagnostic status with an accuracy of 76–85%.
Temporal Dynamics and Developmental Maturation of Salience, Default and Central-Executive Network Interactions Revealed by Variational Bayes Hidden Markov Modeling
A novel Variational Bayesian Hidden Markov Model (VB-HMM) is developed to investigate dynamic temporal properties of interactions between salience (SN), default mode (DMN), and central executive (CEN) networks—three brain systems that play a critical role in human cognition.
Ensemble Hidden Markov Models with Extended Observation Densities for Biosignal Analysis
A variational learning approach to try and improve on the maximum-likelihood estimators for HMMs with observation models that are from the exponential family of distributions, namely the Kullback-Leibler divergence.

Uncovering hidden brain state dynamics that regulate performance and decision-making during cognition
A novel Bayesian algorithm is used to track dynamic transitions between hidden neural states in human brain activity and to relate brain dynamics with behavior, demonstrating the power of switching dynamical systems models for investigating hidden dynamic brain states and functional interactions underlying human cognition.

It is shown that fusing dimensionality reduction and time-varying FC estimation in one single step can avoid these problems and outperform alternative approaches, facilitating the quantification of transient communication in the brain.
Tracking whole-brain connectivity dynamics in the resting state.
It is suggested that the study of time-varying aspects of FC can unveil flexibility in the functional coordination between different neural systems, and that the exploitation of these dynamics in further investigations may improve the understanding of behavioral shifts and adaptive processes.
A Bayesian Approach for Estimating Dynamic Functional Network Connectivity in fMRI Data
This work proposes a principled Bayesian approach to dynamic functional connectivity, which is based on the estimation of time varying networks, and applies it to simulated task -based fMRI data, showing how the approach allows the decoupling of the task-related activations and the functional connectivity states.
