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

Selective visual attention describes the tendency of visual processing to be confined largely
to stimuli that are relevant to behavior. It is among the most fundamental of cognitive …

The two basic phenomena that define the problem of visual attention can be illustrated in a
simple example. Consider the arrays shown in each panel of Figure 1. In a typical …

1. An oculomotor delayed-response task was used to examine the spatial memory functions
of neurons in primate prefrontal cortex. Monkeys were trained to fixate a central spot during …

First published in 1995, The Visual Brain in Action remains a seminal publication in the
cognitive sciences. It presents a model for understanding the visual processing underlying …

Publisher Summary Basal ganglia contribute to a wide variety of behavioral functions,
including skeletomotor, oculomotor, cognitive, and limbic processes. This chapter focuses …

An analysis of response latencies shows that when an image is presented to the visual
system, neuronal activity is rapidly routed to a large number of visual areas. However, the …

The prefrontal cortex makes up almost a quarter of the human brain, and it expanded
dramatically during primate evolution. The Neurobiology of the Prefrontal Cortex presents a …

A typical scene contains many different objects that, because of the limited processing
capacity of the visual system, compete for neural representation. The competition among …

Unilateral neglect reflects a disturbance in the spatial distribution of directed attention. A
review of unilateral neglect syndromes in monkeys and humans suggests that four cerebral …
