Active inference, eye movements and oculomotor delays
This paper considers the problem of sensorimotor delays in the optimal control of (smooth)
eye movements under uncertainty. Specifically, we consider delays in the visuo-oculomotor …

More is not always better: adaptive gain control explains dissociation between perception and action
Moving objects generate motion information at different scales, which are processed in the
visual system with a bank of spatiotemporal frequency channels. It is not known how the …

Lawful tracking of visual motion in humans, macaques, and marmosets in a naturalistic, continuous, and untrained behavioral context
Much study of the visual system has focused on how humans and monkeys integrate moving
stimuli over space and time. Such assessments of spatiotemporal integration provide …

A neural representation of naturalistic motion-guided behavior in the zebrafish brain
All animals must transform ambiguous sensory data into successful behavior. This requires
sensory representations that accurately reflect the statistics of natural stimuli and behavior …

Learning heterogeneous delays in a layer of spiking neurons for fast motion detection
A Grimaldi, LU Perrinet - Biological Cybernetics, 2023 - Springer
The precise timing of spikes emitted by neurons plays a crucial role in shaping the response
of efferent biological neurons. This temporal dimension of neural activity holds significant …

Cortical recurrence supports resilience to sensory variance in the primary visual cortex
Our daily endeavors occur in a complex visual environment, whose intrinsic variability
challenges the way we integrate information to make decisions. By processing myriads of …

A key role of orientation in the coding of visual motion direction
Despite the fundamental importance of visual motion processing, our understanding of how
the brain represents basic aspects of motion is incomplete. While it is generally believed that …

A dual foveal-peripheral visual processing model implements efficient saccade selection
E Daucé, P Albiges, LU Perrinet - Journal of Vision, 2020 - jov.arvojournals.org
We develop a visuomotor model that implements visual search as a focal accuracy-seeking
policy, with the target's position and category drawn independently from a common …

Context effects on smooth pursuit and manual interception of a disappearing target
P Kreyenmeier, J Fooken… - Journal of …, 2017 - journals.physiology.org
In our natural environment, we interact with moving objects that are surrounded by richly
textured, dynamic visual contexts. Yet most laboratory studies on vision and movement show …
