Simultaneous recordings from large neural populations are becoming increasingly common.
An important feature of population activity is the trial-to-trial correlated fluctuation of spike …

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 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 …

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 …

Attention is believed to enhance perception by altering the activity-level correlations
between pairs of neurons. How attention changes neuronal activity correlations is unknown …

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 …

For medical and fundamental reasons, we need to understand adult brain plasticity at
several levels: structural, physiological, and behavioral. Historically, brain plasticity has …

Visual perception depends strongly on spatial context. A profound example is visual
crowding, whereby the presence of nearby stimuli impairs the discriminability of object …

Intrinsic neuronal variability significantly limits information encoding in the primary visual
cortex (V1). Certain stimuli can suppress this intertrial variability to increase the reliability of …

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 …
