The effects of membrane potential oscillations on the excitability of rat hypoglossal motoneurons
Frontiers in Physiology, 2022 Oscillations in membrane potential induced by synaptic inputs and intrinsic ion channel activity play a role in regulating neuronal excitability, but the precise mechanisms underlying their contributions remain largely unknown.

An agent-based model of metabolic signaling oscillations in Bacillus subtilis biofilms. [PDF]
PLoS Computational BiologyMicrobes of nearly every species can form biofilms, communities of cells bound together by a self-produced matrix. It is not understood how variation at the cellular level impacts putatively beneficial, colony-level behaviors, such as cell-to-cell ...

The mitochondrial membrane potential and Ca2+ oscillations in smooth muscle [PDF]
Journal of Cell Science, 2008 Ca2+ uptake by mitochondria might both modulate the cytosolic Ca2+ concentration ([Ca2+]c) and depolarize the mitochondrial membrane potential (ΔΨm) to limit ATP production. To investigate how physiological Ca2+ signaling might affect energy production, ΔΨm was examined during Ca2+ oscillations in smooth muscle cells.

Action Potential: A Vortex Phenomena; Driving Membrane Oscillations [PDF]
Frontiers in Computational Neuroscience, 2020 Hodgkin-Huxley (HH) model has been one of the most successful electrical interpretation of nerve membrane which led to revolutions in the field of computational neuroscience. On the contrary, experimental observations indicate that, an Action Potential (AP) is accompanied with certain physiological changes in the nerve membrane such as, production and ...

Numerical Investigation of T-Shaped Microfluidic Oscillator with Viscoelastic Fluid
Micromachines, 2021 Oscillatory flow has many applications in micro-scaled devices. The methods of realizing microfluidic oscillators reported so far are typically based on the impinging-jet and Coanda effect, which usually require the flow Reynolds number to be at least at

The ionic mechanism of membrane potential oscillations and membrane resonance in striatal LTS interneurons [PDF]
Journal of Neurophysiology, 2016 Striatal low-threshold spiking (LTS) interneurons spontaneously transition to a depolarized, oscillating state similar to that seen after sodium channels are blocked. In the depolarized state, whether spontaneous or induced by sodium channel blockade, the neurons express a 3- to 7-Hz oscillation and membrane impedance resonance in the same frequency ...

Dynamics of sodium current mediated early afterdepolarizations
Heliyon, 2017 Early afterdepolarizations (EADs) have been attributed to two primary mechanisms: 1) recovery from inactivation of the L-type calcium (Ca) channel and/or 2) spontaneous Ca release, which depolarizes the membrane potential through the electrogenic sodium ...
