  • Inflection, Canards and Folded Singularities in Excitable Systems: Application to a 3D FitzHugh–Nagumo Model 

    Uria-Albizuri J.; Desroches M.; Krupa M.; Rodrigues S. (Journal of Nonlinear Science, 2020-09-07)
    Specific kinds of physical and biological systems exhibit complex Mixed-Mode Oscillations mediated by folded-singularity canards in the context of slow-fast models. The present manuscript revisits these systems, specifically ...
  • Why we should use topological data analysis in ageing: Towards defining the “topological shape of ageing” 

    Fülöp T.; Desroches M.; Cohen A.; Santos F.A.N.; Rodrigues S. (Mechanisms of Ageing and Development, 2020-10-27)
    Living systems are subject to the arrow of time; from birth, they undergo complex transformations (self-organization) in a constant battle for survival, but inevitably ageing and disease trap them to death. Can ageing be ...
  • Targeting Infectious Agents as a Therapeutic Strategy in Alzheimer’s Disease 

    Fülöp T.; Munawara U.; Larbi A.; Desroches M.; Rodrigues S.; Catanzaro M.; Guidolin A.; Khalil A.; Bernier F.; Barron A.E.; Hirokawa K.; Beauregard P.B.; Dumoulin D.; Bellenger J.-P.; Witkowski J. M.; Frost E. (CNS Drugs, 2020-05-26)
    Alzheimer’s disease (AD) is the most prevalent dementia in the world. Its cause(s) are presently largely unknown. The most common explanation for AD, now, is the amyloid cascade hypothesis, which states that the cause of ...
  • Neuron-glial Interactions 

    De Pitta M. (Encyclopedia of Computational Neuroscience, 2020-06-07)
    Although lagging behind classical computational neuroscience, theoretical and computational approaches are beginning to emerge to characterize different aspects of neuron-glial interactions. This chapter aims to provide ...
  • Grigorchuk-Gupta-Sidki groups as a source for Beauvile surfaces 

    Sükran G.; Uria-Albizuri J. (Groups, Geometry, and Dynamics, 2020-04-14)
    If $G$ is a Grigorchuk-Gupta-Sidki group defined over a $p$-adic tree, where p is an odd prime, we study the existence of Beauville surfaces associated to the quotients of $G$ by its level stabilizers $st_G(n)$. We prove ...
  • A theoretical approach for the electrochemical characterization of ciliary epithelium 

    Sacco R.; Guidoboni G.; Jerome J.W.; Bonifazi G.; Marazzi N.M.; Vercellin A.C.V.; Lang M.S.; Harris A. (Life, 2020-01-23)
    The ciliary epithelium (CE) is the primary site of aqueous humor (AH) production, which results from the combined action of ultrafiltration and ionic secretion. Modulation of ionic secretion is a fundamental target for ...
  • Computing Multipersistence by Means of Spectral Systems 

    Guidolin A.; Divasón J.; Romero A.; Vaccarino F. (Proceedings of the 2019 on International Symposium on Symbolic and Algebraic Computation, 2019-07-08)
    In their original setting, both spectral sequences and persistent homology are algebraic topology tools defined from filtrations of objects (e.g. topological spaces or simplicial complexes) indexed over the set Z of integer ...
  • A roadmap to integrate astrocytes into Systems Neuroscience 

    Kastanenka Ksenia V.; Poskanzer Kira E.; Galea Elena; Moreno-Bote R.; De Pittà M.; Perea G.; Eraso-Pichot A.; Masgrau R. (Glia, 2019-05-06)
    Systems Neuroscience is still mainly a neuronal field, despite the plethora of evidence supporting the fact that astrocytes modulate local neural circuits, networks, and complex behaviors. In this article, we sought to ...
  • Metastable resting state brain dynamics 

    beim Graben P.; Jimenez-Marin A.; Diez I.; Cortes J.M.; Desroches M.; Rodrigues S. (Frontiers in Computational Neuroscience, 2019-09-06)
    Metastability refers to the fact that the state of a dynamical system spends a large amount of time in a restricted region of its available phase space before a transition takes place, bringing the system into another state ...
  • Conductance-Based Refractory Density Approach for a Population of Bursting Neurons 

    Chizhov A.; Campillo F.; Desroches M.; Guillamon A; Rodrigues S. (Bulletin of Mathematical Biology, 2019)
    The conductance-based refractory density (CBRD) approach is a parsimonious mathematical-computational framework for modeling interact- ing populations of regular spiking neurons, which, however, has not been yet extended ...
  • Anticipation via canards in excitable systems 

    Köksal Ersöz E.; Desroches M.; Mirasso C.; Rodrigues S. (Chaos: An Interdisciplinary Journal of Nonlinear Science, 2019-01-14)
    Neurons can anticipate incoming signals by exploiting a physiological mechanism that is not well understood. This article offers a novel explanation on how a receiver neuron can predict the sender’s dynamics in a ...
  • Pro-C congruence properties for groups of rooted tree automorphisms 

    Garrido A.; Uria-Albizuri J. (Archiv der Mathematik, 2018-11-21)
    We propose a generalisation of the congruence subgroup problem for groups acting on rooted trees. Instead of only comparing the profinite completion to that given by level stabilizers, we also compare pro-$\mathcal{C}$ ...
  • Multi-GGS groups have the congruence subgroup property 

    Garrido A.; Uria-Albizuri J. (Proceedings of the Edinburgh Mathematical Society, 2018-11-08)
    We generalize the result about the congruence subgroup property for GGS-groups to the family of multi-GGS-groups; that is, all multi-GGS-groups except the one defined by the constant vector have the congruence subgroup ...
