Binocular coordination of saccades: development, aging and cerebral substrate
Journal of Eye Movement Research, 2008 The origin of binocular coordination of saccades (central, peripheral) and the role of learning remain controversial (Hering vs Helmholtz). We will present evidence for learning: in young children (5 years) horizontal saccades are poorly yoked ...

Visual stimulation of saccades in magnetically tethered Drosophila [PDF]
, 2006 Flying fruit flies, Drosophila melanogaster, perform `body saccades', in which they change heading by about 90° in roughly 70 ms. In free flight, visual expansion can evoke saccades, and saccade-like turns are triggered by similar stimuli in tethered ...

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.

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.

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.

Frontal Eye Field Neurons Assess Visual Stability Across Saccades [PDF]
, 2012 The image on the retina may move because the eyes move, or because something in the visual scene moves. The brain is not fooled by this ambiguity. Even as we make saccades, we are able to detect whether visual objects remain stable or move.

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.

Atypical modulation of face-elicited saccades in autism spectrum disorder in a double-step saccade paradigm [PDF]
, 2011 Atypical development of face processing is a major characteristic in autism spectrum disorder (ASD), which could be due to atypical interactions between subcortical and cortical face processing. The current study investigated the saccade planning towards

Vision Research, 2006 Saccades are necessary for optimal vision. Little is known about saccades in children. We recorded saccades using an infrared eye tracker in 39 children, aged 8-19 years. Participants made saccades to visual targets that stepped 10 degrees or 15 degrees horizontally and 5 degrees or 10 degrees vertically at unpredictable time intervals.

Multiple parietal reach regions in humans: cortical representations for visual and proprioceptive feedback during on-line reaching [PDF]
, 2009 Reaching toward a visual target involves at least two sources of information. One is the visual feedback from the hand as it approaches the target.
