Active Inference and Intentional Behaviour
Karl J. Friston, Tommaso Salvatori, Takuya Isomura +10
Recent advances in theoretical biology suggest that basal cognition and sentient behaviour are emergent properties of in vitro cell cultures and neuronal networks, respectively. Su…
Minimum-phase property of the hemodynamic response function, and implications for Granger Causality in fMRI
Leonardo Novelli, Lionel Barnett, Anil Seth +1
Granger Causality (GC) is widely used in neuroimaging to estimate directed statistical dependence among brain regions using time series of brain activity. An important issue is tha…
Spectral Dynamic Causal Modelling: A Didactic Introduction and its Relationship with Functional Connectivity
Leonardo Novelli, Karl Friston, Adeel Razi
We present a didactic introduction to spectral Dynamic Causal Modelling (DCM), a Bayesian state-space modelling approach used to infer effective connectivity from non-invasive neur…
Hierarchical Bayesian inference for community detection and connectivity of functional brain networks
Lingbin Bian, Nizhuan Wang, Leonardo Novelli +2
Most functional magnetic resonance imaging studies rely on estimates of hierarchically organized functional brain networks whose segregation and integration reflect the cognitive a…
A mathematical perspective on edge-centric brain functional connectivity
Leonardo Novelli, Adeel Razi
Edge time series are increasingly used in brain functional imaging to study the node functional connectivity (nFC) dynamics at the finest temporal resolution while avoiding sliding…
Identification of brain states, transitions, and communities using functional MRI
Lingbin Bian, Tiangang Cui, B. T. Thomas Yeo +3
Brain function relies on a precisely coordinated and dynamic balance between the functional integration and segregation of distinct neural systems. Characterizing the way in which…
Parcels and particles: Markov blankets in the brain
Karl J. Friston, Erik D. Fagerholm, Tahereh S. Zarghami +4
At the inception of human brain mapping, two principles of functional anatomy underwrote most conceptions - and analyses - of distributed brain responses: namely functional segrega…
The connected brain: Causality, models and intrinsic dynamics
Adeel Razi, Karl Friston
Recently, there have been several concerted international efforts - the BRAIN initiative, European Human Brain Project and the Human Connectome Project, to name a few - that hope t…
