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 …

Selective visual attention is subserved by selective neuronal synchronization, entailing
precise orchestration among excitatory and inhibitory cells. We tentatively identified these as …

Attention to a stimulus enhances both neuronal responses and gamma frequency synchrony
in visual area V4, both of which should increase the impact of attended information on …

Attention selectively enhances the influence of neuronal responses conveying information
about relevant sensory attributes. Accumulating evidence suggests that this selective …

Extensive theoretical and experimental work on the neuronal correlates of visual attention
raises two hypotheses about the underlying mechanisms. The first hypothesis, named …

Selective attention lends relevant sensory input priority access to higher-level brain areas
and ultimately to behavior. Recent studies have suggested that those neurons in visual …

In a crowded visual scene, we typically employ attention to select stimuli that are
behaviorally relevant. Two likely cortical sources of top-down attentional feedback to cortical …

Spike and local field potential activity were recorded simultaneously from multiple sites in
primary visual cortex of strabismic cats, while monocular stimulation alternated with …

A fundamental feature of information processing in neocortex is the ability of individual
neurons to adapt to changes in incoming stimuli. It is increasingly being understood that …

Recordings from area V4 of monkeys have revealed that when the focus of attention is on a
visual stimulus within the receptive field of a cortical neuron, two distinct changes can occur …
