Saccadic undershoot is not inevitable: Saccades can be accurate
Vision Research, 1986 Saccades normally take the eye 90% of the way to a target, followed by a 10% corrective saccade. An exception to this rule occurs with the range effect. When targets appear in a set of positions, saccades overshoot the near positions and undershoot the far. This phenomenon, previously reported, was confirmed with more accurate methods. The range effect

Saccadic instabilities and voluntary saccadic behaviour
Experimental Brain Research, 2005Primary gaze fixation is never perfectly stable but can be interrupted by involuntary, conjugate saccadic intrusions (SI). SI have a high prevalence in the normal population and are characterised by a horizontal fast eye movement away from the desired eye position, followed, after a variable duration, by a return saccade or drift.

Saccadic Inhibition in Voluntary and Reflexive Saccades
Journal of Cognitive Neuroscience, 2002Abstract The present study investigated saccadic inhibition in both voluntary and stimulus-elicited saccades. Two experiments examined saccadic inhibition caused by an irrelevant flash occurring subsequent to target onset. In each trial, participants were required to perform a single saccade following the presentation of a black target ...

Visualization by heat maps is a powerful technique for showing frequently visited areas in displayed stimuli. However, by aggregating the spatio-temporal data, heat maps lose the information about the transitions between fixations, i.e., the saccades.

A review of the literature revealed that foveating saccades were found to be faster than other fast eye movements (FEMs) except optokinetic nystagmus (OKN) quick phase. In the present experiment, foveating saccades were compared to OKN quick phase in humans and were found to have higher maximum speeds and shorter durations. Unlike previous experiments,

Contextual saccade adaptation induced by sequential saccades
Journal of Neurophysiology, 2022This study reveals a new type of contextual saccade adaptation: sequential saccades are able to induce contextual saccade adaptation when direction, amplitude, or the existence of preceding and following saccades are used as contexts. These novel findings are also consistent with the idea that saccades made in a sequence are planned concurrently ...

Saccades are rapid eye movements that assist vision by pointing the fovea of the retina, which contains the highest density of photoreceptors, at features of interest in the visual environment. A great deal is now known about the properties and neurobiology of saccades in both health and disease states.

Is saccadic suppression really saccadic?
Vision Research, 1971Abstract Visual thresholds were measured during voluntary saccades of 8° under different conditions. From the experimental data the contributions of the “smearing” and the propre suppression were evaluated. It was found that the suppression disappears when the luminance of the screen was 4 × 10 −2 nt. On the contrary, the suppression increases when
