Reproducibility via neural fields of visual illusions induced by localized stimuli

no code implementations17 Jan 2024 Cyprien Tamekue, Dario Prandi, Yacine Chitour

The aim is to understand and model the visual phenomena observed in these experiments, emphasising their nonlinear nature.

Cortical origins of MacKay-type visual illusions: A case for the non-linearity

no code implementations9 Dec 2022 Cyprien Tamekue, Dario Prandi, Yacine Chitour

To study the interaction between retinal stimulation by redundant geometrical patterns and the cortical response in the primary visual cortex (V1), we focus on the MacKay effect (Nature, 1957) and Billock and Tsou's experiments (PNAS, 2007).

Reproducing sensory induced hallucinations via neural fields

1 code implementation8 Jul 2022 Cyprien Tamekue, Dario Prandi, Yacine Chitour

In this work, we focus on pattern formation in the visual cortex when the cortical activity is driven by a geometric visual hallucination-like stimulus.

Null controllability of the parabolic spherical Grushin equation

no code implementations27 Jan 2021 Cyprien Tamekue

We investigate the null controllability property of the parabolic equation associated with the Grushin operator defined by the canonical almost-Riemannian structure on the 2-dimensional sphere $\mathbb S^2$.
