Are the visual transients from microsaccades helpful? Measuring the influences of small saccades on contrast sensitivity
Like all saccades, microsaccades cause both spatial and temporal changes in the input to the retina. In space, recent studies have shown that these small shifts precisely relocate a narrow (smaller than the foveola) high-acuity retinal locus on the stimulus. However, it has long been questioned whether the temporal modulations resulting from microsaccades are also beneficial for vision. To addr...
متن کاملContrast sensitivity revealed by microsaccades.
Microsaccades are small rapid and involuntary eye movements that occur during fixation in an apparently stochastic manner. They are known to be inhibited in response to sensory transients, with a time course that depends on the stimulus parameters and attention. However, the temporal precision of their onsets and the degree to which they can be used to assess the response of the visual system t...
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...
