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

Theta and gamma frequency oscillations occur in the same brain regions and interact with
each other, a process called cross-frequency coupling. Here, we review evidence for the …

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 …

The thalamus is globally connected with distributed cortical regions, yet the functional
significance of this extensive thalamocortical connectivity remains largely unknown. By …

A hallmark of electrophysiological brain activity is its 1/f-like spectrum–power decreases with
increasing frequency. The steepness of this 'roll-off'is approximated by the spectral …

In this review, we present a survey on Korsakoff's syndrome (KS), a residual syndrome in
patients who suffered from a Wernicke encephalopathy (WE) that is predominantly …

Cognition results from interactions among functionally specialized but widely distributed
brain regions; however, neuroscience has so far largely focused on characterizing the …

Selective attention mechanisms route behaviorally relevant information through large-scale
cortical networks. Although evidence suggests that populations of cortical neurons …

Sensory perception depends on the context in which a stimulus occurs. Prevailing models
emphasize cortical feedback as the source of contextual modulation. However, higher order …

The ventro-lateral pulvinar is reciprocally connected with the visual areas of the ventral
stream that are important for object recognition. To understand the mechanisms of attentive …
