Response sub-additivity and variability quenching in visual cortex
Sub-additivity and variability are ubiquitous response motifs in the primary visual cortex (V1).
Response sub-additivity enables the construction of useful interpretations of the visual …

Neuronal variability reflects probabilistic inference tuned to natural image statistics
Neuronal activity in sensory cortex fluctuates over time and across repetitions of the same
input. This variability is often considered detrimental to neural coding. The theory of neural …

Representation of visual uncertainty through neural gain variability
Uncertainty is intrinsic to perception. Neural circuits which process sensory information must
therefore also represent the reliability of this information. How they do so is a topic of debate …

Feature representation under crowding in macaque V1 and V4 neuronal populations
Visual perception depends strongly on spatial context. A profound example is visual
crowding, whereby the presence of nearby stimuli impairs the discriminability of object …

Excitation creates a distributed pattern of cortical suppression due to varied recurrent input
Dense local, recurrent connections are a major feature of cortical circuits, yet how they affect
neurons' responses has been unclear, with some studies reporting weak recurrent effects …

Stimulus complexity shapes response correlations in primary visual cortex
Spike count correlations (SCCs) are ubiquitous in sensory cortices, are characterized by rich
structure, and arise from structured internal dynamics. However, most theories of visual …
