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.

Epilepsia Open, EarlyView., 2022 Abstract Epilepsy is a heterogeneous disorder characterized by spontaneous seizures and behavioral comorbidities. The underlying mechanisms of seizures and epilepsy across various syndromes lead to diverse clinical presentation and features. Similarly, animal models of epilepsy arise from numerous dissimilar inciting events.

Reward Prediction Error Modulates Saccade Vigor
Journal of Neuroscience, 2019 Movement vigor, defined as the reciprocal of the latency from availability of reward to its acquisition, changes with reward magnitude: movements exhibit shorter reaction time and increased velocity when they are directed toward more rewarding stimuli ...

Modeling the Triggering of Saccades, Microsaccades, and Saccadic Intrusions [PDF]
Frontiers in Neurology, 2018 When we explore a static visual scene, our eyes move in a sequence of fast eye movements called saccades, which are separated by fixation periods of relative eye stability. Based on uncertain sensory and cognitive inputs, the oculomotor system must decide, at every moment, whether to initiate a saccade or to remain in the fixation state.

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 ...

Saccadic adaptation in 10-41 month-old children
Frontiers in Human Neuroscience, 2016 When saccade amplitude becomes systematically inaccurate, adaptation mechanisms gradually decrease or increase it until accurate saccade targeting is recovered. Adaptive shortening and adaptive lengthening of saccade amplitude rely on separate mechanisms

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 ...

Visual System: ‘S’ is not for Saccades [PDF]
Current Biology, 2002 Coloured flashes that are visible only to the short-wavelength-sensitive S cones interfere with shifts of visual attention but not with shifts of gaze (saccades). Attention and gaze must therefore be directed by different visual sub-systems.

Human-level saccade detection performance using deep neural networks
bioRxiv, 2018 Saccades are ballistic eye movements that rapidly shift gaze from one location of visual space to another. Detecting saccades in eye movement recordings is important not only for studying the neural mechanisms underlying sensory, motor, and cognitive ...

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
