A model for cooperative gating of L-type Ca2+ channels and its effects on cardiac alternans dynamics.

open access: yesPLoS Computational Biology, 2018
In ventricular myocytes, membrane depolarization during the action potential (AP) causes synchronous activation of multiple L-type CaV1.2 channels (LTCCs), which trigger the release of calcium (Ca2+) from the sarcoplasmic reticulum (SR).

Inositol trisphosphate‐induced membrane potential oscillations in Xenopus oocytes.

open access: yesThe Journal of Physiology, 1988
1. The role of inositol 1,4,5‐trisphosphate (Ins1,4,5P3) in controlling the membrane potential oscillations induced by acetylcholine in Xenopus oocytes was investigated by studying the effect of injecting Ins1,4,5P3. 2. Perfusing Xenopus oocytes with low concentrations of acetylcholine (less than or equal to 1 x 10(‐7) M) induced regular oscillations ...

Spike-timing dependent plasticity and feed-forward input oscillations produce precise and invariant spike phase-locking

open access: yesFrontiers in Computational Neuroscience, 2011
In the hippocampus and the neocortex, the coupling between local field potential (LFP) oscillations and the spiking of single neurons can be highly precise, across neuronal populations and cell types. Spike phase (i.e.

Paired burst stimulation causes GABAA receptor-dependent spike firing facilitation in CA1 of rat hippocampal slices

open access: yesFrontiers in Cellular Neuroscience, 2016
The theta oscillation (4–8 Hz) is a pivotal form of oscillatory activity in the hippocampus that is intermittently concurrent with gamma (25–100 Hz) burst events.

Biophysical basis of the sound analogue membrane potential that underlies coincidence detection in the barn owl

open access: yesFrontiers in Computational Neuroscience, 2013
Interaural time difference (ITD), or the difference in timing of a sound wave arriving at the two ears, is a fundamental cue for sound localization. A wide variety of animals have specialized neural circuits dedicated to the computation of ITDs.

Using molecular dynamics simulation to examine the evolution of blood barrier structure in the presence of different electric fields

open access: yesInternational Journal of Thermofluids
Membrane disruption refers to increasing cell membrane permeability. This state may be transient, allowing the cell to regain its function, or it can be lasting, resulting in the cell's demise.

Deoxynivalenol-induced circadian CLOCK oscillation disruption promotes RAW264.7 macrophage immunosenescence by unleashing cGAS–STING signaling

open access: yesEcotoxicology and Environmental Safety
Although deoxynivalenol (DON)-induced immunotoxicity is well-established, the mechanisms driving DON-mediated immunosenescence remain poorly understood.

Self‐Sustained Oscillations in MoS2 Optomechanical Resonators for VHF Optical Radio

open access: yesAdvanced Photonics Research
We investigate self‐sustained oscillations on microdrum resonators manufactured with molybdenum disulfide, under continuous‐wave laser excitation. Control over these oscillations is demonstrated building a simple radio‐over‐laser link.

Acetylcholine-induced membrane potential oscillations in the intact lens.

open access: yesInvestigative ophthalmology & visual science, 1998
Factors that interfere with the acetylcholine signaling system have long been implicated in cataract. The authors sought to investigate the nature of the electrical response of the intact rabbit lens to acetylcholine.Membrane potential (Vm) and electrical conductance (Gm) were monitored in the isolated, perifused lens by a technique utilizing two ...
