Eye cannot see it: The interference of subliminal distractors on saccade metrics [PDF]

, 2009
The present study investigated whether subliminal (unconsciously perceived) visual information influences eye movement metrics, like saccade trajectories and endpoints.

Saccadic Suppression of Displacement Does Not Reflect a Saccade-Specific Bias to Assume Stability

Vision, 2019
Across saccades, small displacements of a visual target are harder to detect and their directions more difficult to discriminate than during steady fixation.

The influence of saccades on visual masking

Journal of Vision, 2010
Visual masking is a well known phenomenon in which the visibility of a stimulus, the target, is reduced by the rapid presentation of either a subsequent or preceding stimulus, called the mask. In a typical masking paradigm participants are not allowed to move their eyes and asked to maintain fixation throughout the trial.

Inhibition of masked primes as revealed by saccade curvature

Vision Research, 2010
In masked priming, responses are often speeded when primes are similar to targets ('positive compatibility effect'). However, sometimes similarity of prime and target impairs responses ('negative compatibility effect'). A similar distinction has been found for the curvature of saccade trajectories.

The role of the ventrolateral frontal cortex in inhibitory oculomotor control [PDF]

, 2007
It has been proposed that the inferior/ventrolateral frontal cortex plays a critical role in the inhibitory control of action during cognitive tasks.However, the contribution of this region to the control of eye movements has not been clearly established.

A Stochastic Optimal Control Model with Internal Feedback and Velocity Tracking for Saccades [PDF]

, 2020
A stochastic optimal control based model with velocity tracking and internal feedback for saccadic eye movements is presented in this paper. Recent evidence from neurophysiological studies of superior colliculus suggests the presence of a dynamic input to the saccade generation system that encodes saccade velocity, rather than just the saccade ...

An fMRI study of parietal cortex involvement in the visual guidance of locomotion [PDF]

, 2010
Locomoting through the environment typically involves anticipating impending changes in heading trajectory in addition to maintaining the current direction of travel.

Structural neural networks subserving oculomotor function in first-episode schizophrenia [PDF]

, 2004
BACKGROUND: Smooth pursuit and antisaccade abnormalities are well documented in schizophrenia, but their neuropathological correlates remain unclear. METHODS: In this study, we used statistical parametric mapping to investigate the relationship between

Saccadic gain adaptation is predicted by the statistics of natural fluctuations in oculomotor function

Frontiers in Computational Neuroscience, 2012
Due to multiple factors such as fatigue, muscle strengthening, and neural plasticity, the responsiveness of the motor apparatus to neural commands changes over time.

Saccade Mechanisms for Image Classification, Object Detection and Tracking [PDF]

arXiv, 2022
We examine how the saccade mechanism from biological vision can be used to make deep neural networks more efficient for classification and object detection problems. Our proposed approach is based on the ideas of attention-driven visual processing and saccades, miniature eye movements influenced by attention. We conduct experiments by analyzing: i) the
