Evaluating the neurophysiological evidence for predictive processing as a model of perception
For many years, the dominant theoretical framework guiding research into the neural origins
of perceptual experience has been provided by hierarchical feedforward models, in which …

[HTML][HTML] Uncertainty and stress: Why it causes diseases and how it is mastered by the brain
A Peters, BS McEwen, K Friston - Progress in neurobiology, 2017 - Elsevier
The term 'stress'–coined in 1936–has many definitions, but until now has lacked a
theoretical foundation. Here we present an information-theoretic approach–based on the …

The graphical brain: Belief propagation and active inference
This paper considers functional integration in the brain from a computational perspective.
We ask what sort of neuronal message passing is mandated by active inference—and what …

Layer and rhythm specificity for predictive routing
In predictive coding, experience generates predictions that attenuate the feeding forward of
predicted stimuli while passing forward unpredicted “errors.” Different models have …

[HTML][HTML] Connectivity-based fixel enhancement: Whole-brain statistical analysis of diffusion MRI measures in the presence of crossing fibres
In brain regions containing crossing fibre bundles, voxel-average diffusion MRI measures
such as fractional anisotropy (FA) are difficult to interpret, and lack within-voxel single fibre …

Large-scale cortical networks for hierarchical prediction and prediction error in the primate brain
According to predictive-coding theory, cortical areas continuously generate and update
predictions of sensory inputs at different hierarchical levels and emit prediction errors when …
