The Role of Neck Input in Producing Corrective Saccades in the Head Impulse Test

Frontiers in Neurology, 2022
BackgroundThe head impulse test is a valuable clinical test that can help identify peripheral vestibular dysfunction by observing corrective saccades that return the eyes to the target of interest.

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 ...

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.

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 ...

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

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.

Saccades in children

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.
