Geometry of spiking patterns in early visual cortex: A topological data analytic approach
Guidolin, A.; Desroches, M.
; Victor, J. D.; Purpura, K. P.; Rodrigues, S. (2022-11-16)
; Victor, J. D.; Purpura, K. P.; Rodrigues, S. (2022-11-16)
In the brain, spiking patterns live in a high-dimensional space of neurons and time. Thus, determining the intrinsic structure of this space presents a theoretical and experimental challenge. To address this challenge, we ...
Interaction Mechanism Between the HSV-1 Glycoprotein B and the Antimicrobial Peptide Amyloid-β
Bourgade, K.; Frost, E.; Dupuis, G.; Witkowski, J.M.; Laurent, B.; Calmettes, C.; Ramassamy, C.; Desroches, M.; Rodrigues, S.; Fülöp, T. (2022-09-19)
; Rodrigues, S.; Fülöp, T. (2022-09-19)
Background: Unravelling the mystery of Alzheimer's disease (AD) requires urgent resolution given the worldwide increase of the aging population. There is a growing concern that the current leading AD hypothesis, the amyloid ...
A phenomenological model for interfacial water near hydrophilic polymers
Earls, A.; Calderer, M.-C.; Desroches, M.; Zarnescu, A.; Rodrigues, S. (2022-06-30)
; Zarnescu, A.; Rodrigues, S. (2022-06-30)
We propose a minimalist phenomenological model for the ‘interfacial water’ phenomenon that
occurs near hydrophilic polymeric surfaces. We achieve this by combining a Ginzburg–Landau
approach with Maxwell’s equations which ...
Immunosenescence and Altered Vaccine Efficiency in Older Subjects: A Myth Difficult to Change
Fülöp, T.; Larbi, A.; Pawelec, G.; Cohen, A.; Provost, G.; Khalil, A.; Lacombe, G.; Rodrigues, S.; Desroches, M.; Hirokawa, K.; Franceschi, C.; Witkowski, J.M. (2022-04-01)
; Desroches, M.; Hirokawa, K.; Franceschi, C.; Witkowski, J.M. (2022-04-01)
Organismal ageing is associated with many physiological changes, including differences in the immune system of most animals. These differences are often considered to be a key cause of age-associated diseases as well as ...
Classification of bursting patterns: A tale of two ducks
Desroches, M.; Rinzel, J.; Rodrigues, S. (2022-01-20)
; Rinzel, J.; Rodrigues, S. (2022-01-20)
Bursting is one of the fundamental rhythms that excitable cells can generate either in response to incoming stimuli or intrinsically. It has been a topic of intense research in computational biology for several decades. ...
Hyperactivation of monocytes and macrophages in MCI patients contributes to the progression of Alzheimer's disease
Munawara, U.; Catanzaro, M.; Xu, W.; Tan, C.; Hirokawa, K.; Bosco, N.; Dumoulin, D.; Khalil, A.; Larbi, A.; Lévesque, S.; Ramassamy, C.; Barron, A.; Cunnane, S.; Beauregard, P.; Bellenger, J.P.; Rodrigues, S.; Desroches, M.; Witkowski, J.M.; Laurent, B.; Frost, E.; Fülöp, T. (2021-12-01)
; Desroches, M.; Witkowski, J.M.; Laurent, B.; Frost, E.; Fülöp, T. (2021-12-01)
Background: Alzheimer’s disease (AD) is the most common neurodegenerative disease ultimately manifesting as clinical dementia. Despite considerable effort and ample experimental data, the role of neuroinflammation related ...
Targeting Impaired Antimicrobial Immunity in the Brain for the Treatment of Alzheimer’s Disease
Fülöp, T.; Tripathi, S.; Rodrigues, S.; Desroches, M.; Bunt, T.; Eiser, A.; Bernier, F.; Beauregard, P.; Barron, A.; Khalil, A.; Plotka, A.; Hirokawa, K.; Larbi, A.; Bocti, C.; Laurent, B.; Frost, E.; Witkowski, J. (2021-05-04)
; Rodrigues, S.; Desroches, M.; Bunt, T.; Eiser, A.; Bernier, F.; Beauregard, P.; Barron, A.; Khalil, A.; Plotka, A.; Hirokawa, K.; Larbi, A.; Bocti, C.; Laurent, B.; Frost, E.; Witkowski, J. (2021-05-04)
Alzheimer’s disease (AD) is the most common form of dementia and aging is the most common risk factor for developing the disease. The etiology of AD is not known but AD may be considered as a clinical syndrome with multiple ...
Spike-adding and reset-induced canard cycles in adaptive integrate and fire models
Desroches, M.; Kowalczyk, P.; Rodrigues, S. (2021-05-03)
; Kowalczyk, P.; Rodrigues, S. (2021-05-03)
We study a class of planar integrate and fire (IF) models called adaptive integrate and fire (AIF) models, which possesses an adaptation vari- able on top of membrane potential, and whose subthreshold dynamics is piece- ...
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. (2020-10-27)
; Cohen, A.; Santos, F.A.N.; Rodrigues, S. (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 ...
Inflection, Canards and Folded Singularities in Excitable Systems: Application to a 3D FitzHugh–Nagumo Model
Uria-Albizuri, J.; Desroches, M.; Krupa, M.; Rodrigues, S. (2020-09-07)
; Krupa, M.; Rodrigues, S. (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 ...
