Modeling sequential cognitive states via population level cortical dynamics
M Virginia Bolelli, Luca Greco, Dario Prandi
In this work, we present a mathematical model for cyclic and sequential patterns of brain activity, combining heteroclinic dynamics with discrete neural-field models. We first show…
Individuation of 3D perceptual units from neurogeometry of binocular cells
Maria Virginia Bolelli, Giovanna Citti, Alessandro Sarti +1
We model the functional architecture of the early stages of three-dimensional vision by extending the neurogeometric sub-Riemannian model for stereo-vision introduced in \cite{BCSZ…
Neural field equations with time-periodic external inputs and some applications to visual processing
Maria Virginia Bolelli, Dario Prandi
The aim of this work is to present a mathematical framework for the study of flickering inputs in visual processing tasks. When combined with geometric patterns, these inputs influ…
Good continuation in 3D: the neurogeometry of stereo vision
Maria Virginia Bolelli, Giovanna Citti, Alessandro Sarti +1
Classical good continuation for image curves is based on position and orientation. It is supported by the columnar organization of cortex, by psychophysical experiments, and b…
