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.

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.

Gain control of saccadic eye movements is probabilistic [PDF]

, 2019
Saccades are rapid eye movements that orient the visual axis toward objects of interest to allow their processing by the central, highacuity retina. Our ability to collect visual information efficiently relies on saccadic accuracy, which is limited by a ...

Change blindness: eradication of gestalt strategies [PDF]

, 2011
Arrays of eight, texture-defined rectangles were used as stimuli in a one-shot change blindness (CB) task where there was a 50% chance that one rectangle would change orientation between two successive presentations separated by an interval.

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.

Biases in the perceived timing of perisaccadic perceptual and motor events [PDF]

, 2006
Subjects typically experience the temporal interval immediately following a saccade as longer than a comparable control interval. One explanation of this effect is that the brain antedates the perceptual onset of a saccade target to around the time of ...

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
