Life and understanding: the origins of “understanding” in self-organizing nervous systems

YM Yufik, K Friston - Frontiers in Systems Neuroscience, 2016 - frontiersin.org
This article is motivated by a formulation of biotic self-organization in Friston, where the
emergence of “life” in coupled material entities (eg, macromolecules) was predicated on …

Prefrontal neural dynamics in consciousness

U León-Domínguez, J León-Carrión - Neuropsychologia, 2019 - Elsevier
Abstract The Prefrontal Cortex (PFC) is one of the principal brain regions studied in
consciousness. Previous investigations suggest that the PFC is an important neural hub in …

Differential heterogenesis and the emergence of semiotic function

A Sarti, G Citti, D Piotrowski - Semiotica, 2019 - degruyter.com
In this study, we analyse the notion of “differential heterogenesis” proposed by Deleuze and
Guattari on a morphogenetic perspective. We propose a mathematical framework to …

Visual illusions via neural dynamics: Wilson–Cowan-type models and the efficient representation principle

M Bertalmío, L Calatroni, V Franceschi… - Journal of …, 2020 - journals.physiology.org
We reproduce suprathreshold perception phenomena, specifically visual illusions, by Wilson–
Cowan (WC)-type models of neuronal dynamics. Our findings show that the ability to …

A Sarti, G Citti, D Piotrowski - 2022 - books.google.com
This book describes about unlike usual differential dynamics common in mathematical
physics, heterogenesis is based on the assemblage of differential constraints that are …

Analysis of vessel connectivities in retinal images by cortically inspired spectral clustering

M Favali, S Abbasi-Sureshjani… - Journal of Mathematical …, 2016 - Springer
Retinal images provide early signs of diabetic retinopathy, glaucoma, and hypertension.
These signs can be investigated based on microaneurysms or smaller vessels. The …

Functional architecture of M1 cells encoding movement direction

C Mazzetti, A Sarti, G Citti - Journal of Computational Neuroscience, 2023 - Springer
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 …

A geometric model of multi-scale orientation preference maps via Gabor functions

E Baspinar, G Citti, A Sarti - Journal of Mathematical Imaging and Vision, 2018 - Springer
In this paper we present a new model for the generation of orientation preference maps in
the primary visual cortex (V1), considering both orientation and scale features. First we …

Nilpotent approximations of sub-Riemannian distances for fast perceptual grouping of blood vessels in 2D and 3D

EJ Bekkers, D Chen, JM Portegies - Journal of mathematical imaging and …, 2018 - Springer
We propose an efficient approach for the grouping of local orientations (points on vessels)
via nilpotent approximations of sub-Riemannian distances in the 2D and 3D roto-translation …
