Systematic diagonal and vertical errors in antisaccades and memory-guided saccades

Journal of Eye Movement Research, 2010
Studies of memory-guided saccades in monkeys show an upward bias, while studies of antisaccades in humans show a diagonal effect, a deviation of endpoints toward the 45° diagonal.

Evidence that indirect inhibition of saccade initiation improves saccade accuracy [PDF]

, 2010
Saccadic eye-movements to a visual target are less accurate if there are distracters close to its location (local distracters). The addition of more distracters, remote from the target location (remote distracters), invokes an involuntary increase in the

Gain control of saccadic eye movements is probabilistic [PDF]

, 2019
Saccades are rapid eye movements that orient the visual axis toward objects of interest to allow their processing by the central, highacuity retina. Our ability to collect visual information efficiently relies on saccadic accuracy, which is limited by a ...

Looking for discriminating is different from looking for looking's sake. [PDF]

PLoS ONE, 2012
Recent studies provide evidence for task-specific influences on saccadic eye movements. For instance, saccades exhibit higher peak velocity when the task requires coordinating eye and hand movements.

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 ...

A Vertical Asymmetry in Saccades

Journal of Eye Movement Research, 2015
Visual exploration of natural scenes imposes demands that differ between the upper and the lower visual hemifield. Yet little is known about how ocular motor performance is affected by the location of visual stimuli or the direction of a behavioural ...

Pre-saccadic perception: separate time courses for enhancement and spatial pooling at the saccade target [PDF]

, 2017
We interact with complex scenes using eye movements to select targets of interest. Studies have shown that the future target of a saccadic eye movement is processed differently by the visual system.

Saccadic Direction Errors are Associated with Impulsive Compulsive Behaviours in Parkinson’s Disease Patients

Journal of Parkinson’s Disease, 2019
Fifteen individuals with Parkinson’s disease (PD) and impulsive compulsive behaviours (PD+ICB) were compared to 15 PD patients without ICBs (PD-ICB) and 15 healthy controls (HC) on a pro-saccades and an anti-saccades task to assess if ICBs are associated

Saccade-induced image motion cannot account for post-saccadic enhancement of visual processing in primate MST

Frontiers in Systems Neuroscience, 2015
Primates use saccadic eye movements to make gaze changes. In many visual areas, including the dorsal medial superior temporal area (MSTd) of macaques, neural responses to visual stimuli are reduced during saccades but enhanced afterwards.

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
