Dynamic models of large-scale brain activity
M Breakspear - Nature neuroscience, 2017 - nature.com
Movement, cognition and perception arise from the collective activity of neurons within
cortical circuits and across large-scale systems of the brain. While the causes of single …

Functional and effective connectivity: a review
KJ Friston - Brain connectivity, 2011 - liebertpub.com
Over the past 20 years, neuroimaging has become a predominant technique in systems
neuroscience. One might envisage that over the next 20 years the neuroimaging of …

Macroscopic resting-state brain dynamics are best described by linear models
It is typically assumed that large networks of neurons exhibit a large repertoire of nonlinear
behaviours. Here we challenge this assumption by leveraging mathematical models derived …

Thinking through other minds: A variational approach to cognition and culture
The processes underwriting the acquisition of culture remain unclear. How are shared
habits, norms, and expectations learned and maintained with precision and reliability across …

[HTML][HTML] A guide to group effective connectivity analysis, part 1: First level analysis with DCM for fMRI
Abstract Dynamic Causal Modelling (DCM) is the predominant method for inferring effective
connectivity from neuroimaging data. In the 15 years since its introduction, the neural …

[HTML][HTML] Bayesian model reduction and empirical Bayes for group (DCM) studies
This technical note describes some Bayesian procedures for the analysis of group studies
that use nonlinear models at the first (within-subject) level–eg, dynamic causal models–and …

Allostatic self-efficacy: A metacognitive theory of dyshomeostasis-induced fatigue and depression
This paper outlines a hierarchical Bayesian framework for interoception,
homeostatic/allostatic control, and meta-cognition that connects fatigue and depression to …

Cultural affordances: Scaffolding local worlds through shared intentionality and regimes of attention
In this paper we outline a framework for the study of the mechanisms involved in the
engagement of human agents with cultural affordances. Our aim is to better understand how …

The salience network is responsible for switching between the default mode network and the central executive network: replication from DCM
N Goulden, A Khusnulina, NJ Davis, RM Bracewell… - Neuroimage, 2014 - Elsevier
With the advent of new analysis methods in neuroimaging that involve independent
component analysis (ICA) and dynamic causal modelling (DCM), investigations have …
