The flash-lag effect as a motion-based predictive shift
MA Khoei, GS Masson, LU Perrinet - PLoS computational biology, 2017 - journals.plos.org
Due to its inherent neural delays, the visual system has an outdated access to sensory
information about the current position of moving objects. In contrast, living organisms are …

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 …

Speed-selectivity in retinal ganglion cells is sharpened by broad spatial frequency, naturalistic stimuli
Motion detection represents one of the critical tasks of the visual system and has motivated a
large body of research. However, it remains unclear precisely why the response of retinal …

A normalization mechanism for estimating visual motion across speeds and scales
Interacting with the natural environment leads to complex stimulations of our senses. Here
we focus on the estimation of visual speed, a critical source of information for the survival of …

Bayesian modeling of motion perception using dynamical stochastic textures
A common practice to account for psychophysical biases in vision is to frame them as
consequences of a dynamic process relying on optimal inference with respect to a …
