Exploration of the functional consequences of fixational eye movements in the absence of a fovea. [PDF]
, 2020 A recent theory posits that ocular drifts of fixational eye movements serve to reformat the visual input of natural images, so that the power of the input image is equalized across a range of spatial frequencies.

Increased microsaccade rate in individuals with ADHD traits [PDF]
, 2017 Microsaccades are involuntary, small, jerk-like eye-movements with high-velocity that are observed during fixation. Abnormal microsaccade rates and characteristics have been observed in a number of psychiatric and developmental disorders.

Do microsaccades track shifting but not sustaining covert attention?
Proceedings of the National Academy of Sciences of the United States of America, 2023 Microsaccades—small fixational eye movements—have been shown to parallel the direction of covert shifts of attention (1, 2), consistent with a key role of the brain’s oculomotor system in orchestrating covert attention (3).

Scaling of Horizontal and Vertical Fixational Eye Movements
, 2004 Eye movements during fixation of a stationary target prevent the adaptation of the photoreceptors to continuous illumination and inhibit fading of the image. These random, involuntary, small, movements are restricted at long time scales so as to keep the

The behavioural and neurophysiological modulation of microsaccades in monkeys [PDF]
, 2009 Systematic modulations of microsaccades have been observed in humans during covert orienting. We show here that monkeys are a suitable model for studying the neurophysiology governing these modulations of microsaccades.

Monocular microsaccades are visual-task related [PDF]
, 2016 During visual fixation, we constantly move our eyes. These microscopic eye movements are composed of tremor, drift, and microsaccades. Early studies concluded that microsaccades, like larger saccades, are binocular and conjugate, as expected from Hering ...

Contrast sensitivity revealed by microsaccades
Journal of Vision, 2015 Microsaccades are small rapid and involuntary eye movements that occur during fixation in an apparently stochastic manner. They are known to be inhibited in response to sensory transients, with a time course that depends on the stimulus parameters and attention. However, the temporal precision of their onsets and the degree to which they can be used to

Toward a model of microsaccade generation: The case of microsaccadic inhibition
Journal of Vision, 2008 Microsaccades are one component of the small eye movements that constitute fixation. Their implementation in the oculomotor system is unknown. To better understand the physiological and mechanistic processes underlying microsaccade generation, we studied microsaccadic inhibition, a transient drop of microsaccade rate, in response to irrelevant visual ...

The effects of fixation target size and luminance on microsaccades and square-wave jerks [PDF]
, 2013 A large amount of classic and contemporary vision studies require subjects to fixate a target. Target fixation serves as a normalizing factor across studies, promoting the field’s ability to compare and contrast experiments.
