Effort drives saccade selection

eLife
What determines where to move the eyes? We recently showed that pupil size, a well-established marker of effort, also reflects the effort associated with making a saccade (‘saccade costs’).

Modulation of saccade trajectories during sequential saccades

Journal of Neurophysiology, 2021
We show that in saccade sequences, saccade trajectory is modulated in the direction of the preceding saccade and away from the following saccade. The magnitude of this effect is correlated with preceding and following saccade amplitude. This confirms that programming of sequential saccades overlaps.

The parallel programming of landing position in saccadic eye movement sequences [PDF]

, 2020
Saccadic eye movements occur in sequences, gathering new information about the visual environment to support successful task completion. Here we examine the control of these saccadic sequences and specifically the extent to which the spatial aspects of ...

Biases in the perceived timing of perisaccadic perceptual and motor events [PDF]

, 2006
Subjects typically experience the temporal interval immediately following a saccade as longer than a comparable control interval. One explanation of this effect is that the brain antedates the perceptual onset of a saccade target to around the time of ...

Giving subjects the eye and showing them the finger: socio-biological cues and saccade generation in the anti-saccade task. [PDF]

, 2012
Pointing with the eyes or the finger occurs frequently in social interaction to indicate direction of attention and one's intentions. Research with a voluntary saccade task (where saccade direction is instructed by the colour of a fixation point ...

Spatial eye–hand coordination during bimanual reaching is not systematically coded in either LIP or PRR [PDF]

, 2018
Significance When we reach for something, we also look at it. If we reach for two objects at once, one with each hand, we look first at one and then the other. It is not known which brain areas underlie this coordination.

Adaptation and mislocalization fields for saccadic outward adaptation in humans

Journal of Eye Movement Research, 2010
Adaptive shortening of a saccade influences the metrics of other saccades within a spatial window around the adapted target. Within this adaptation field visual stimuli presented before an adapted saccade are mislocalized in proportion to the change of ...

The programming of sequences of saccades [PDF]

, 2019
Saccadic eye movements move the high-resolution fovea to point at regions of interest. Saccades can only be generated serially (i.e., one at a time). However, what remains unclear is the extent to which saccades are programmed in parallel (i.e., a series

Seeing and looking: Evidence for developmental and stimulus-dependent changes in infant scanning efficiency.

PLoS ONE, 2022
Though previous work has examined infant attention across a variety of tasks, less is known about the individual saccades and fixations that make up each bout of attention, and how individual differences in saccade and fixation patterns (i.e., scanning ...

Separate representations of target and timing cue locations in the supplementary eye fields [PDF]

, 2009
When different stimuli indicate where and when to make an eye movement, the brain areas involved in oculomotor control must selectively plan an eye movement to the stimulus that encodes the target position and also encode the information available from ...
