Neuronal control of fixation and fixational eye movements
Ocular fixation is a dynamic process that is actively controlled by many of the same brain
structures involved in the control of eye movements, including the superior colliculus …

How is visual salience computed in the brain? Insights from behaviour, neurobiology and modelling
Inherent in visual scene analysis is a bottleneck associated with the need to sequentially
sample locations with foveating eye movements. The concept of a 'saliency …

Spatial frequency sensitivity in macaque midbrain
Visual brain areas exhibit tuning characteristics well suited for image statistics present in our
natural environment. However, visual sensation is an active process, and if there are any …

Enhanced neural processing by covert attention only during microsaccades directed toward the attended stimulus
Attention can be" covertly" directed without eye movements; yet, even during fixation, there
are continuous microsaccades (MSs). In areas V4 and IT of macaques, we found that firing …

Sharper, stronger, faster upper visual field representation in primate superior colliculus
Visually guided behavior in three-dimensional environments entails handling immensely
different sensory and motor conditions across retinotopic visual field locations: peri-personal …

Microsaccades track location-based object rehearsal in visual working memory
E de Vries, F van Ede - Eneuro, 2024 - eneuro.org
Besides controlling eye movements, the brain's oculomotor system has been implicated in
the control of covert spatial attention and the rehearsal of spatial information in working …

Human-level saccade detection performance using deep neural networks
Saccades are ballistic eye movements that rapidly shift gaze from one location of visual
space to another. Detecting saccades in eye movement recordings is important not only for …

Motor selection dynamics in FEF explain the reaction time variance of saccades to single targets
CK Hauser, D Zhu, TR Stanford, E Salinas - Elife, 2018 - elifesciences.org
In studies of voluntary movement, a most elemental quantity is the reaction time (RT)
between the onset of a visual stimulus and a saccade toward it. However, this RT …

The inevitability of visual interruption
A Buonocore, ZM Hafed - Journal of Neurophysiology, 2023 - journals.physiology.org
For successful adaptive behavior, exogenous environmental events must be sensed and
reacted to as efficiently as possible. In the lab, the mechanisms underlying such efficiency …

The foveal visual representation of the primate superior colliculus
A defining feature of the primate visual system is its foveated nature. Processing of foveal
retinal input is important not only for high-quality visual scene analysis but also for ensuring …
