Titre : Dynamics of Myelin Remodeling in Brain Function,

Résumé : Many neuronal axons in the brain are covered by myelin — a compacted cell membrane that wraps around axons in discrete sheaths. Myelin is critical for proper brain function, facilitating the rapid and efficient propagation of electrical signals. The structural remodeling of myelin represents an emerging facet of neural plasticity. This spatiotemporal process influences the dynamics of individual neurons and, consequently, neural networks. Examples of myelin remodeling include changes in the lengths of myelinated and unmyelinated segments, as well as the formation or removal of myelin sheaths. In this talk, we will present a mathematical model, formulated as a system of partial differential equations, to capture the dynamics of myelin plasticity along individual axons. Additionally, we will explore how demyelination — the pathological removal of myelin — disrupts the faithful propagation of electrical signals. Finally, we will introduce a mathematical framework for modeling myelin plasticity in neural networks. This approach, based on systems of delay differential equations, offers insights into the collective dynamics of neural networks.
