Rewards are crucial objects that induce learning, approach behavior, choices, and
emotions. Whereas emotions are difficult to investigate in animals, the learning function is …

We review evidence for partially segregated networks of brain areas that carry out different
attentional functions. One system, which includes parts of the intraparietal cortex and …

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 …

Visual search, a vital task for humans and animals, has also become a common and
important tool for studying many topics central to active vision and cognition ranging from …

To make a visual discrimination, the brain must extract relevant information from the retina,
represent appropriate variables in the visual cortex and read out this representation to …

Assigning meaning to words, sounds, and objects requires stored conceptual knowledge
plus executive mechanisms that shape semantic retrieval according to the task or context …

The planning, control and execution of eye movements in 3D space relies on a distributed
system of cortical and subcortical brain regions. Within this network, the Eye Fields have …

The ability to select information that is relevant to current behavioral goals is the hallmark of
voluntary attention and an essential part of our cognition. Attention tasks are a prime …

The derivation, exposition, and justification of the Selective Tuning model of vision and
attention. Although William James declared in 1890," Everyone knows what attention is," …

Conscious perception of the visual world depends on neural activity at all levels of the visual
system from the retina to regions of parietal and frontal cortex. Neurons in early visual areas …
