This paper provides a concise description of the free energy principle, starting from a
formulation of random dynamical systems in terms of a Langevin equation and ending with a …

Recent neurophysiological and neuroanatomical studies suggest a close interaction
between sensory and motor processes across the neocortex. Here, I propose that the …

We review a recent shift in conceptions of interoception and its relationship to hierarchical
inference in the brain. The notion of interoceptive inference means that bodily states are …

How is it that thoroughly physical material beings such as ourselves can think, dream, feel,
create and understand ideas, theories and concepts? How does mere matter give rise to all …

Cognitive function requires the coordination of neural activity across many scales, from
neurons and circuits to large-scale networks. As such, it is unlikely that an explanatory …

Active inference is a normative principle underwriting perception, action, planning, decision-
making and learning in biological or artificial agents. From its inception, its associated …

This paper offers an active inference account of choice behaviour and learning. It focuses on
the distinction between goal-directed and habitual behaviour and how they contextualise …

This paper describes a path integral formulation of the free energy principle. The ensuing
account expresses the paths or trajectories that a particle takes as it evolves over time. The …

Modern psychology has long focused on the body as the basis of the self. Recently,
predictive processing accounts of interoception (perception of the body 'from within') have …

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 …
