Full textThis thesis explores two distinct control theory applications in different scientific domains: physics and neuroscience. The first application focuses on the null controllability of the parabolic, spherical Baouendi-Grushin equation. In contrast, the second application involves the mathematical description of the MacKay-type visual illusions, focusing on the MacKay effect and Billock and Tsou's psychophysical experiments by controlling the one-layer Amari-type neural fields equation. Additionally, intending to study input-to-state stability and robust stabilization, the thesis investigates the existence of equilibrium in a multi-layer neural fields population model of Wilson-Cowan, specifically when the sensory input is a proportional feedback acting only on the system's state of the populations of excitatory neurons.In the first part, we investigate the null controllability properties of the parabolic equation associated with the Baouendi-Grushin operator defined by the canonical almost-Riemannian structure on the 2-dimensional sphere. It presents a degeneracy at the equator of the sphere. We provide some null controllability properties of this equation to this curved setting, which generalize that of the parabolic Baouendi-Grushin equation defined on the plane.Regarding neuroscience, initially, the focus lies on the description of visual illusions for which the tools of bifurcation theory and even multiscale analysis appear unsuitable. In our study, we use the neural fields equation of Amari-type in which the sensory input is interpreted as a cortical representation of the visual stimulus used in each experiment. It contains a localised distributed control function that models the stimulus's specificity, e.g., the redundant information in the centre of MacKay's funnel pattern (``MacKay rays'') or the fact that visual stimuli in Billock and Tsou's experiments are localized in the visual field.Always within the framework of neurosciences, we investigate the existence of equilibrium in a multi-layers neural fields population model of Wilson-Cowan when the sensory input is a proportional feedback that acts only on the system's state of the population of excitatory neurons. There, we provide a mild condition on the response functions under which such an equilibrium exists. The interest of this work lies in its application in studying the disruption of pathological brain oscillations associated with Parkinson's disease when stimulating and measuring only the population of excitatory neurons
