Linking fast and slow: the case for generative models
Johan Medrano, Karl J. Friston, Peter Zeidman
A pervasive challenge in neuroscience is testing whether neuronal connectivity changes over time due to specific causes, such as stimuli, events, or clinical interventions. Recent…
One person's modus ponens...: Comment on "The Markov blanket trick: On the scope of the free energy principle and active inference" by Raja and colleagues (2021)
Maxwell J. D Ramstead
In this comment on "The Markov blanket trick: On the scope of the free energy principle and active inference" by Raja and colleagues (2021) in Physics of Life Reviews, I argue that…
Ranking of Communities in Multiplex Spatiotemporal Models of Brain Dynamics
James Wilsenach, Katie Warnaby, Charlotte M. Deane +1
As a relatively new field, network neuroscience has tended to focus on aggregate behaviours of the brain averaged over many successive experiments or over long recordings in order…
Frontal effective connectivity increases with task demands and time on task: a Dynamic Causal Model of electrocorticogram in macaque monkeys
Katharina Wegner, Charles R. E. Wilson, Emmanuel Procyk +4
We apply Dynamic Causal Models to electrocorticogram recordings from two macaque monkeys performing a problem-solving task that engages working memory, and induces time-on-task eff…
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…
Is the free-energy principle a formal theory of semantics? From variational density dynamics to neural and phenotypic representations
Maxwell Ramstead, Karl Friston, Ines Hipolito
The aim of this paper is twofold: (1) to assess whether the construct of neural representations plays an explanatory role under the variational free-energy principle and its coroll…
