In exploring the visual scene we make about three saccadic eye movements per second.
During each fixation, in addition to analyzing the object at which we are looking, a decision …

More than one third of the human brain is devoted to the processes of seeing-vision is after
all the main way in which we gather information about the world. But human vision is a …

Organisms control their visual worlds by moving their eyes, heads, and bodies. This control
of “gaze” or “looking” is key to survival and intelligence, but our investigation of the …

Significant advances in cognitive neuroscience can be achieved by combining techniques
used to measure behavior and brain activity with neural modeling. Here we apply this …

Publisher Summary In naturally occurring search situations, eye movements form the most
effective way of sampling the visual field. This chapter analyzes the concept of “covert visual …

How do patterns of neural activity in the motor cortex contribute to the planning of a
movement? A recent theory developed for single movements proposes that the motor cortex …

Humans shift their gaze to a new location several times per second. It is still unclear what
determines where they look next. Fixation behavior is influenced by the low-level salience of …

Actions often require the selection of a specific goal amongst a range of possibilities, like
when a softball player must precisely position her glove to field a fast-approaching ground …

Existing theories of movement planning suggest that it takes time to select and prepare the
actions required to achieve a given goal. These theories often appeal to circumstances …

Making a saccadic eye movement involves two decisions, the decision to initiate the
saccade and the selection of the visual target of the saccade. Here we provide a theoretical …
