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 …

Evidence is provided for a new conceptualization of the connectivity and functions of the
cingulate cortex in emotion, action, and memory. The anterior cingulate cortex receives …

The orbitofrontal cortex and amygdala are involved in emotion and in motivation, but the
relationship between these functions performed by these brain structures is not clear. To …

Recent evidence has demonstrated that environmental sampling is a fundamentally
rhythmic process. Both perceptual sensitivity during covert spatial attention and the …

In natural behaviour, animals actively interrogate their environments using endogenously
generated 'question-and-answer'strategies. However, in laboratory settings participants …

In this article, we challenge the usefulness of “attention” as a unitary construct and/or neural
system. We point out that the concept has too many meanings to justify a single term, and …

Classic studies of spatial attention assumed that its neural and behavioral effects were
continuous over time. Recent behavioral studies have instead revealed that spatial attention …

Neuronal representations change as associations are learned between sensory stimuli and
behavioral actions. However, it is poorly understood whether representations for learned …

This article proposes that biologically plausible theories of behavior can be constructed by
following a method of “phylogenetic refinement,” whereby they are progressively elaborated …

Visual attention enables us to selectively prioritize or suppress information in the
environment. Prominent models concerned with the control of visual attention differentiate …
