Microsaccades as an Overt Measure of Covert Attention Shifts
Vision Research, 2002 Microsaccades, or tiny eye movements that take place during periods of fixation, have long been thought to be random artifacts of the oculomotor system. Here we demonstrate a possible link between microsaccades and covert attention shifts.

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

ABSTRACT Brain 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 ...

Binocular quantification and characterization of microsaccades
Graefe’s Archive for Clinical and Experimental Ophthalmology, 2002The significance of microsaccades in the visual process has been discussed for more than 50 years. However, only a few studies have measured microsaccades binocularly, and detailed quantification and characterization of these small movements are needed in order to further understand their nature.The amplitude, velocity, acceleration and direction of ...

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.

Microsaccades for Neuromorphic Stereo Vision
2018Depth perception through stereo vision is an important feature of biological and artificial vision systems. While biological systems can compute disparities effortlessly, it requires intensive processing for artificial vision systems. The computing complexity resides in solving the correspondence problem – finding matching pairs of points in the two ...

Effects of driving time on microsaccadic dynamics
Experimental Brain Research, 2014Driver fatigue is a common cause of car accidents. Thus, the objective detection of driver fatigue is a first step toward the effective management of fatigue-related traffic accidents. Here, we investigated the effects of driving time, a common inducer of driver fatigue, on the dynamics of fixational eye movements.

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.
