Monocular microsaccades: Do they really occur?
Small saccades, known as microsaccades, occur frequently during fixation. Several recent studies have argued that a considerable fraction of these movements are present in the traces from one eye only. This claim contrasts with the findings of older reports, which concluded that microsaccades, like larger saccades, are virtually always binocular events. Here we examined the characteristics of s...
متن کاملMicrosaccades are modulated by both attentional demands of a visual discrimination task and background noise.
Microsaccades are miniature saccades occurring once or twice per second during visual fixation. While microsaccades and saccades share similarities at the oculomotor level, the functional roles of microsaccades are still debated. In this study, we examined the hypothesis that the microsaccadic activity is affected by the type of noisy background during the execution of a particular discriminati...
متن کاملMicrosaccades and Visual-Spatial Working Memory
The ability to remember and manipulate information is essential to human cognitive processes. Working memory (WM) is pervasive as a workspace for mental processes that make up momentary, explicit consciousness. Not only does the function of WM include simple temporary storage, or short-term memory (STM), but also more complex processes that manipulate and transform stored representations (Miyak...
متن کاملAlteration of Visual Perception prior to Microsaccades
Gaze fixation is an active process, with the incessant occurrence of tiny eye movements, including microsaccades. While the retinal consequences of microsaccades may be presumed minimal because of their minute size, a significant perceptual consequence of these movements can also stem from active extraretinal mechanisms associated with corollaries of their motor generation. Here I show that pri...
متن کاملMicrosaccades Counteract Visual Fading during Fixation
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, and so the role of microsaccades remains u...
