Microsaccadic flutter is a rare symptomatic saccadic oscillation that has been reported only twice previously. Here we describe 5 patients with this disorder. The oscillation is horizontal, has a frequency of 15-30 Hz, an amplitude of 0.1-0.5 degrees, and cannot be seen with the unaided eye. It is usually not associated with any underlying neurological

ABSTRACTBrain circuitry that controls where we look also contributes to attentional focusing of visual contents outside of current fixation or contents held within the spatial layout of working memory. A behavioural manifestation of the contribution of oculomotor brain circuitry to selective attention comes from modulations in microsaccade direction ...

Inhibition of return in microsaccades
Experimental Brain Research, 2004Inhibition of return (IOR) is the term used to describe the phenomenon whereby stimuli appearing at recently attended locations are reacted to less efficiently than stimuli appearing at locations that have not yet been attended. In the present study, we employed a typical IOR paradigm with peripheral uninformative cues while participants maintained ...

Microsaccades generated during car driving
2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013Microsaccades together with drift and tremor are fixational eye movements that are generated when we try to fixate our gaze on a visual target. Besides their function in vision to prevent neural adaptation to unchanging retinal image, microsaccades have been studied in neuroscience as an indicator of attentional states for the last decade.

Microsaccades as Indicators for Early-Stage Parkinson's Disease: An Explainable AI Approach
Eye Tracking Research & ApplicationAbnormal fixational eye movements are frequently observed in individuals with Parkinson’s disease (PD). While these involuntary movements have the potential to serve as objective indicators for early-stage PD screening, the specific role of microsaccades

Moving gratings and microsaccades
Journal of the Optical Society of America A, 1990This paper reports an extended study of anomalous (enhanced) sensitivity to moving gratings in the range of 1-10 cycles per degree, at high temporal frequencies (greater than 20 Hz), i.e., in the high-frequency corner of the spatiotemporal threshold surface. The effect is very robust.

Saccades and Microsaccades Coupling During Free-Throw Shots in Basketball Players.
Journal of Sport & Exercise Psychology (JSEP)We investigated the role of saccades and microsaccades when different levels of basketball players were engaged in an ecological free-throw condition. All participants made more correct than incorrect shoots, with a movement time initiation shorter in ...

Visual oddballs induce prolonged microsaccadic inhibition
Experimental Brain Research, 2006Eyes never stop moving. Even when asked to maintain the eyes at fixation, the oculomotor system produces small and rapid eye movements called microsaccades, at a frequency of about 1.5-2 s(-1). The frequency of microsaccades changes when a stimulus is presented in the visual field, showing a stereotyped response pattern consisting of an early ...

The article is devoted to the description and analysis of a computer model that was created by D. S. Lebedev to demonstrate the possibility of a positive effect of fixation microsaccadic eye movements on the perception of small stimuli.
