Can microsaccade rate predict drug response?
In 22 human subjects we measured microsaccade count across 60 brief fixation trials both pre- and post- administration of 300mg of caffeine. There was a statistically significant reduction in average microsaccade count post-caffeine administration, with ...

Microsaccades Do Not Give Rise to a Conscious Feeling of Agency for Their Sensorimotor Consequences in Visual Perception [PDF]
Feeling 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 ...

Effects of others’ gaze and facial expression on an observer’s microsaccades and their association with ADHD tendencies [PDF]
Background The aim of this study was to examine the effect of others’ gaze on an observer’s microsaccades. We also aimed to conduct preliminary investigations on the relationship between the microsaccadic response to a gaze and a gazer’s facial ...

Microsaccades strongly modulate but do not directly cause the EEG N2pc marker of spatial attention. [PDF]
The 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 ...

Microsaccades are small-amplitude, fixational eye movements that are largely thought to be involuntary. Here, the authors demonstrate that monkeys (and humans) can be easily trained to respond to a remembered target location with a volitional ...

Microsaccades Are Coupled to Heartbeat [PDF]
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.

Oculomotor inhibition markers of working memory load [PDF]
Involuntary eye movements occur constantly even during fixation and were shown to convey information about cognitive processes. They are inhibited momentarily in response to external stimuli (oculomotor inhibition, OMI), with a time and magnitude that ...

Stable Microsaccades and Microsaccade-Induced Global Alpha Band Phase Reset Across the Life Span [PDF]
To understand the effect of aging on microsaccade functions and brain physiologic responses, we quantified microsaccades and their physiologic correlates (including their interaction with alpha band brain oscillation) in normal subjects of different ages.Twenty-two normally sighted young (18 to 29 years), 22 middle-aged (31 to 55 years), and 22 elderly

Microsaccades counteract visual fading during fixation [PDF]
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,

Investigating Arousal, Saccade Preparation, and Global Luminance Effects on Microsaccade Behavior
Microsaccades, small saccadic eye movements occurring during fixation, have been suggested to be modulated by various sensory, cognitive, and affective processes relating to arousal.
