Microsaccades, Drifts, Hopf Bundle and Neurogeometry

Journal of Imaging, 2022
The first part of the paper contains a short review of the image processing in early vision is static, when the eyes and the stimulus are stable, and in dynamics, when the eyes participate in fixation eye movements. In the second part, we give an interpretation of Donders’ and Listing’s law in terms of the Hopf fibration of the 3-sphere over the 2 ...

Temporal unpredictability increases error monitoring as revealed by EEG–EMG investigation

Psychophysiology, Volume 61, Issue 2, February 2024.
Abstract Reacting in an unpredictable context increases error monitoring as evidenced by greater error‐related negativity (ERN), an electrophysiological marker linked to an evaluation of response outcomes. We investigated whether ERN also increased when participants evaluated their responses to events that appeared in unpredictable versus predictable ...

Real-time eye motion correction in phase-resolved OCT angiography with tracking SLO [PDF]

, 2013
In phase-resolved OCT angiography blood flow is detected from phase changes in between A-scans that are obtained from the same location. In ophthalmology, this technique is vulnerable to eye motion. We address this problem by combining inter-B-scan phase-

Microsaccades [PDF]

, 2015
The first thing we do upon waking is open our eyes. Rotating them in our eye sockets, we scan our surroundings and collect the information into a picture in our head. Eye movements can be split into saccades and fixational eye movements, which occur when we attempt to fixate our gaze. The latter consists of microsaccades, drift and tremor.

The effect of retinal image slip on peripheral visual acuity [PDF]

, 2008
Retinal image slip promoted by fixational eye movements prevents image fading in central vision. However, in the periphery a higher amount of movement is necessary to prevent this fading.

Microsaccade-inspired event camera for robotics

Science Robotics
Neuromorphic vision sensors or event cameras have made the visual perception of extremely low reaction time possible, opening new avenues for high-dynamic robotics applications. These event cameras’ output is dependent on both motion and texture. However, the event camera fails to capture object edges that are parallel to the camera motion.

EEG findings of reduced neural synchronization during visual integration in schizophrenia [PDF]

, 2015
Schizophrenia patients exhibit well-documented visual processing deficits. One area of disruption is visual integration, the ability to form global objects from local elements.
