Mathematical model of bursting in dissociated Purkinje neurons [PDF]

, 2013
In vitro, Purkinje cell behaviour is sometimes studied in a dissociated soma preparation in which the dendritic projection has been cleaved. A fraction of these dissociated somas spontaneously burst.

Differences in Sodium Channel Densities in the Apical Dendrites of Pyramidal Cells of the Electrosensory Lateral Line Lobe

Frontiers in Neural Circuits, 2019
Heterogeneity of neural properties within a given neural class is ubiquitous in the nervous system and permits different sub-classes of neurons to specialize for specific purposes.

Emergent synchronous bursting of oxytocin neuronal network [PDF]

, 2008
When young suckle, they are rewarded intermittently with a let-down of milk that results from reflex secretion of the hormone oxytocin; without oxytocin, newly born young will die unless they are fostered. Oxytocin is made by magnocellular hypothalamic

Information Transmission Concept Based Model of Wave Propagation in Discrete Excitable Media

Nonlinear Analysis, 2004
A new information transmission concept based model of excitable media with continuous outputs of the model’s cells and variable excitation time is proposed. Continuous character of the outputs instigates infinitesimal inaccuracies in calculations.

Nonlinear optimal perturbations in a Couette flow: bursting and transition [PDF]

, 2013
This paper provides the analysis of bursting and transition to turbulence in a Couette flow, based on the growth of nonlinear optimal disturbances. We use a global variational procedure to identify such optimal disturbances, defined as those initial ...

Genome-wide kinetic properties of transcriptional bursting in mouse embryonic stem cells

Science Advances, 2020
The kinetic properties of transcriptional bursting were comprehensively analyzed in mouse embryonic stem cells. Transcriptional bursting is the stochastic activation and inactivation of promoters, contributing to cell-to-cell heterogeneity in gene ...

Low-dimensional models of ‘Neuro-glio-vascular unit’ for describing neural dynamics under normal and energy-starved conditions

Frontiers in Neurology, 2016
The motivation of developing simple minimal models for neuro-glio-vascular system arises from a recent modeling study elucidating the bidirectional information flow within the neuro-glio-vascular system having 89 dynamic equations (Chander and ...

Multilevel synchronization of human β-cells networks

Frontiers in Network Physiology, 2023
β-cells within the endocrine pancreas are fundamental for glucose, lipid and protein homeostasis. Gap junctions between cells constitute the primary coupling mechanism through which cells synchronize their electrical and metabolic activities.

Variation de la fertilité des bourgeons pendant le repos végétatif chez le cépage Merlot (Vitis vinifera L.) *

OENO One, 1977
Pendant le repos végétatif, les ébauches des inflorescences des bourgeons subissent une évolution physiologique qui se manifeste par une augmentation de leur poids moyen après le débourrement en conditions contrôlées.
