The visual system is able to process complex movements quickly and efficiently in rich visual scenes thanks to a processing taking place in the retina, the LGN, and the visual cortex. Especially, lateral connectivity enables the generation of waves that only appear when a moving object is present. In our work, we are particularly interested in...

When processing a moving object, the visual system uses several anticipation mechanisms to compensate the delay induced by the photo-transduction [1,2]. On one hand, retinal gain control advances the peak in sensory cells response. On the other hand, due to the lateral connectivity, the activity begins to raise before the moving stimulus enters...

We study motion anticipation in a mean field model of the primary visual cortex (V1) with a realisticretinal input. We assess the ability of this integrated retino-cortical model to reproduce experimentalresults on voltage dye optical imaging (VSDI) signal, in terms of two main quantities used to quantifyanticipation: the latency and the time...

Oculars saccades are very fast eyes movements, occurring about 3 times per second, with a maximum speed of 500°/s, and with a mean speed of 200°/s (Westheimer, 1954). This process is essential to explore a visual scene and capture its information. It also carries our facial recognition and reading abilities. During saccades, the representation...

Oculars saccades are very fast eyes movements, occurring about 3 times per second and with a speed of 300 to 1500 mm/s. This process is essential to explore a visual scene and capture its information. It also carries our facial recognition and reading abilities. During saccades, the representation of the visual scene moves at the same speed...
