Five important trends have emerged from recent work on computational models of focal
visual attention that emphasize the bottom-up, image-based control of attentional …

We frequently reposition our gaze by making rapid ballistic eye movements that are called
saccades. Saccades pose problems for the visual system, because they generate rapid …

We recorded the activity of single neurons in the posterior parietal cortex (area LIP) of two
rhesus monkeys while they discriminated the direction of motion in random-dot visual …

Two tasks were used to evaluate the grain of visual attention, the minimum spacing at which
attention can select individual items. First, observers performed a tracking task at many …

In monkeys, posterior parietal and premotor cortex play an important integrative role in
polymodal motion processing. In contrast, our understanding of the convergence of senses …

We review recent evidence from studies of patients with unilateral neglect and/or extinction,
who suffer from a loss of awareness for stimuli towards the affected side of space. We …

The ability and opportunity to make decisions and carry out effective actions in pursuit of
goals is central to intelligent life. Recent research has provided significant new insights into …

Bottom-up or saliency-based visual attention allows primates to detect nonspecific
conspicuous targets in cluttered scenes. A classical metaphor, derived from …

The processing of visual information combines bottom-up sensory aspects with top-down
influences, most notably attentional processes. Attentional influences have now been …

It is widely agreed that visuospatial orienting attention depends on a network of frontal and
parietal areas in the right hemisphere. It is thought that the visuospatial orienting role of the …
