The collective activity of a population of neurons, beyond the properties of individual cells, is
crucial for many brain functions. A fundamental question is how activity correlations between …

Although we are continuously bombarded with visual input, only a fraction of incoming visual
events is perceived, remembered or acted on. The neural underpinnings of various forms of …

To make adaptive decisions, organisms must appropriately filter sensory inputs, augmenting
relevant signals and suppressing noise. The prefrontal cortex (PFC) partly implements this …

Perception and action are tightly coupled: visual responses at the saccade target are
enhanced right before saccade onset. This phenomenon, presaccadic attention, is a form of …

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 …

Current dominant views hold that perceptual confidence reflects the probability that a
decision is correct. Although these views have enjoyed some empirical support, recent …

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 …

Attention alters three key properties of population neural activity–firing rate, rate variability,
and shared variability between neurons. All three properties are well explained by a single …

The normalization model has been applied to explain neural activity in diverse neural
systems including primary visual cortex (V1). The model's defining characteristic is that the …

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 …
