Top-down feedback in cortex is critical for guiding sensory processing, which has
prominently been formalized in the theory of hierarchical predictive coding (hPC). However …

Surround modulation (SM) is a fundamental property of sensory neurons in many species
and sensory modalities. SM is the ability of stimuli in the surround of a neuron's receptive …

Cognitive functions rely on the coordinated activity of neurons in many brain regions, but the
interactions between cortical areas are not yet well understood. Here we investigated …

This paper outlines a hierarchical Bayesian framework for interoception,
homeostatic/allostatic control, and meta-cognition that connects fatigue and depression to …

The laminar location of the cell bodies and terminals of interareal connections determines
the hierarchical structural organization of the cortex and has been intensively studied …

Animals sense the environment through pathways that link sensory organs to the brain. In
the visual system, these feedforward pathways define the classical feedforward receptive …

Recurrent cortical activity sculpts visual perception by refining, amplifying or suppressing
visual input. However, the rules that govern the influence of recurrent activity remain …

Sensory processing in the neocortex requires both feedforward and feedback information
flow between cortical areas. In feedback processing, higher-level representations provide …

Making inferences from partial information constitutes a critical aspect of cognition. During
visual perception, pattern completion enables recognition of poorly visible or occluded …

Whether small numerical quantities are represented by a special subitizing system that is
distinct from a large-number estimation system has been debated for over a century. Here …
