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

We have come to recognize the brain as a predictive organ, anticipating attributes of the
incoming sensory stimulation to guide perception and action in the service of adaptive …

Classic models of attention suggest that sustained neural firing constitutes a neural correlate
of sustained attention. However, recent evidence indicates that behavioral performance …

I propose that synchronization affects communication between neuronal groups. Gamma-
band (30–90 Hz) synchronization modulates excitation rapidly enough that it escapes 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 …

Visual cortical areas subserve cognitive functions by interacting in both feedforward and
feedback directions. While feedforward influences convey sensory signals, feedback …

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

In recent years high-frequency brain activity in the gamma-frequency band (30–80 Hz) and
above has become the focus of a growing body of work in MEG/EEG research …

Sensory processing, short-term memory, and decision-making often deal with multiple items,
or options, simultaneously. I review evidence suggesting that the brain handles such …

A central motif in neuronal networks is convergence, linking several input neurons to one
target neuron. In visual cortex, convergence renders target neurons responsive to complex …
