Neuronal cortical circuitry comprises feedforward, lateral, and feedback projections, each of
which terminates in distinct cortical layers [1–3]. In sensory systems, feedforward processing …

A key to understanding visual cognition is to determine when, how, and with what
information the human brain distinguishes between visual categories. So far, the dynamics of …

The strongest connections to V1 are fed back from neighbouring area V2 and from a network
of higher cortical areas (eg V3, V5, LOC, IPS and A1), transmitting the results of cognitive …

Competent social organisms will read the social signals of their peers. In primates, the face
has evolved to transmit the organism's internal emotional state. Adaptive action suggests that …

Predictive coding theories propose that the brain creates internal models of the environment
to predict upcoming sensory input. Hierarchical predictive coding models of vision postulate …

This review article addresses the function of the layers of the cerebral cortex. We develop the
perspective that cortical layering needs to be understood in terms of its functional anatomy, …

Closing the structure-function divide is more challenging in the brain than in any other organ
( Lichtman and Denk, 2011 ). For example, in early visual cortex, feedback projections to V1 …

Visual illusions and mental imagery are non-physical sensory experiences that involve
cortical feedback processing in the primary visual cortex. Using laminar functional magnetic …

We humans carry around in our heads rich internal mental models that constitute our
construction of the world, and the relation of that world to us. These models can be expressed at …

Higher visual areas in the occipitotemporal cortex contain discrete regions for face
processing, but it remains unclear if V 1 is modulated by top‐down influences during face …
