Functional architecture of M1 cells encoding movement direction
Caterina Mazzetti, Alessandro Sarti, Giovanna Citti
In this paper we propose a neurogeometrical model of the behaviour of cells of the arm area of the primary motor cortex (M1). We will mathematically express as a fiber bundle the h…
A framework for stereo vision via optimal transport
Mattia Galeotti, Alessandro Sarti, Giovanna Citti
We present a theoretical framework for a stereo vision method via optimal transport tools. We consider two aligned optical systems and we develop the matching between the two pictu…
The cortical V1 transform as a heterogeneous Poisson problem
Alessandro Sarti, Mattia Galeotti, Giovanna Citti
Receptive profiles of V1 cortical cells are very heterogeneous and act by differentiating the stimulus image as operators changing from point to point. A lightness and color consta…
