Attentional shifts bias microsaccade direction but do not cause new microsaccades. [PDF]
Commun PsycholBrain circuitry that controls where we look also contributes to attentional selection of visual contents outside current fixation, or content within the spatial layout of working memory.

Microsaccades Tracking by Secondary Speckle Pattern Analysis. [PDF]
J BiophotonicsHere we propose a not pupil‐dependent microsaccades tracking technique and a novel detection method. We present a proof of concept for detecting microsaccades using a non‐contact laser‐based photonic system recording and processing the temporal changes ...

Common structure of saccades and microsaccades in visual perception. [PDF]
J VisWe obtain large amounts of external information through our eyes, a process often considered analogous to picture mapping onto a camera lens. However, our eyes are never as still as a camera lens, with saccades occurring between fixations and ...

Microsaccade-induced prolongation of saccade latencies depends on microsaccade amplitude [PDF]
Journal of Eye Movement Research, 2008 Fixations consist of small movements including microsaccades, i.e., rapid flicks in eye position that replace the retinal image by up to 1 degree of visual angle.

Microsaccades Are Coupled to Heartbeat [PDF]
The Journal of Neuroscience, 2016 During visual fixation, the eye generates microsaccades and slower components of fixational eye movements that are part of the visual processing strategy in humans. Here, we show that ongoing heartbeat is coupled to temporal rate variations in the generation of microsaccades.

Microsaccades strongly modulate but do not directly cause the EEG N2pc marker of spatial attention. [PDF]
PLoS BiolThe N2pc is a popular human-neuroscience marker of covert and internal spatial attention that occurs 200–300 ms after being prompted to shift attention—a time window also characterized by the spatial biasing of small fixational eye movements known as ...

Stimulus-dependent delay of perceptual filling-in by microsaccades. [PDF]
J VisPerception is a function of both stimulus features and active sensory sampling. The illusion of perceptual filling-in occurs when eye gaze is kept still: visual boundary perception may fail, causing adjacent visual features to remarkably merge into one ...

Microsaccades Do Not Give Rise to a Conscious Feeling of Agency for Their Sensorimotor Consequences in Visual Perception. [PDF]
J CognFeeling of agency (FoA)—the experience of controlling one’s actions and their outcomes—has been widely studied for bodily movements. Here, we investigated if microsaccades—small ballistic eye movements—are equally characterized by FoA and if intention ...

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

Microsaccades counteract visual fading during fixation [PDF]
Journal of Vision, 2005 Our eyes move continually, even while we fixate our gaze on an object. If fixational eye movements are counteracted, our perception of stationary objects fades completely, due to neural adaptation. Some studies have suggested that fixational microsaccades refresh retinal images, thereby preventing adaptation and fading. However, other studies disagree,
