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 Perspective considers the influential notion of a canonical (cortical) microcircuit in light
of recent theories about neuronal processing. Specifically, we conciliate quantitative studies …

Theoretical neuroscience provides a quantitative basis for describing what nervous systems
do, determining how they function, and uncovering the general principles by which they …

We describe a model of visual processing in which feedback connections from a higher-to a
lower-order visual cortical area carry predictions of lower-level neural activities, whereas the …

Predictive coding is a unifying framework for understanding redundancy reduction and
efficient coding in the nervous system. By transmitting only the unpredicted portions of an …

The spatial receptive fields of simple cells in mammalian striate cortex have been
reasonably well described physiologically and can be characterized as being localized …

Rapidly growing empirical evidence supports the hypothesis that the cortex operates near
criticality. Although the confirmation of this hypothesis would mark a significant advance in …

▪ Abstract It has long been assumed that sensory neurons are adapted, through both
evolutionary and developmental processes, to the statistical properties of the signals to …

The repertoire of neural activity patterns that a cortical network can produce constrains the
ability of the network to transfer and process information. Here, we measured activity …

Theoretical studies suggest that primary visual cortex (area V1) uses a sparse code to
efficiently represent natural scenes. This issue was investigated by recording from V1 …
