Microsaccade generation requires a foveal anchor

Journal of Eye Movement Research, 2020
Visual scene characteristics have the ability to affect various aspects of saccade and microsaccade dynamics. For example, blank visual scenes are known to elicit diminished saccade and microsaccade production, compared to natural scenes.

Microsaccades under monocular viewing conditions

Journal of Eye Movement Research, 2009
Among the eye movements during fixation, the function of small saccades occuring quite commonly at fixation is still unclear. It has been reported that a substantial number of these microsaccades seem to occur in only one of the eyes.

Effects of Physical Activity Level on Microsaccade Dynamics During Optic Flow Stimulation in Adults with Type 2 Diabetes [PDF]

Biomedicines
Background: Microsaccades are small fixational eye movements tightly linked to attention and oculomotor control. Although diabetes mellitus is associated with retinal and neural alterations that may impair visuomotor function, the influence of physical ...

Microsaccade Activity During Visuospatial Working Memory in Early-Stage Parkinson’s Disease [PDF]

Journal of Eye Movement Research
Fixational saccadic eye movements (microsaccades) have been associated with cognitive processes, especially in tasks requiring spatial attention and memory. Alterations in oculomotor and cognitive control are commonly observed in Parkinson’s disease (PD),

Monocular microsaccades are visual-task related

, 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 ...

Distinct modulation of microsaccades in motor planning and covert attention [PDF]

Scientific Reports
The degree of overlap between the mechanisms underlying attention control and motor planning remains debated. In this study, we examined whether microsaccades—tiny gaze shifts occurring during fixation—are modulated differently by covert attention and ...

Eyes on hold: motion task difficulty jointly delays microsaccade and pupil responses [PDF]

Scientific Reports
Microsaccades and pupil dynamics exhibit canonical temporal profiles, providing insights into perceptual and cognitive processes. Microsaccades are typically suppressed with respect to expected stimulus onset and followed by a rebound to baseline rates ...

Microsaccades transiently lateralise EEG alpha activity [PDF]

, 2023
The lateralisation of 8–12 Hz alpha activity is a canonical signature of human spatial cognition that is typically studied under strict fixation requirements.

Photoreceptor microsaccades in Drosophila: Three-dimensional charaterisation [PDF]

, 2021
My thesis is about the fruit fly (Drosophila melanogaster) photoreceptor microsaccades. These are light-induced rapid micrometer-sized photoreceptor displacements caused by their photomechanically contracting microvilli.

Microsaccades: a neurophysiological analysis [PDF]

Trends in Neurosciences, 2009
Microsaccades are the largest and fastest of the fixational eye movements, which are involuntary eye movements produced during attempted visual fixation. In recent years, the interaction between microsaccades, perception and cognition has become one of the most rapidly growing areas of study in visual neuroscience.
