Modelling Oscillations of Membrane Potential Difference
2007The oscillation of the membrane potential difference (PD) is considered in terms of one or more ion transporters changing their conductances. For slow oscillations (period greater than about one minute), the transporters could be identified by employing the current–voltage (I/V) technique.

Subthreshold oscillations of the membrane potential: a functional synchronizing and timing device
Journal of Neurophysiology, 19931. Subthreshold membrane potential oscillations have been observed in different types of CNS neurons. In this in vitro study, we examined the possible role of these oscillations by analyzing the responses of neurons from the inferior olivary nucleus to a combined stimulation of sine wave and synaptic potentials. 2.

Simulation of the light-induced oscillations of the membrane potential in Potamogeton leaf cells
The Journal of Membrane Biology, 1993An attempt has been made to simulate the light-induced oscillations of the membrane potential of Potamogeton lucens leaf cells in relation to the apoplastic pH changes. Previously it was demonstrated that the membrane potential of these cells can be described in terms of proton movements only.

Caffeine-induced oscillations of the membrane potential inAplysia neurons
Neurophysiology, 2000It has been found in culturedAplysia neurons, including L7 and L2–L6 neurons, that bath application of 40 mM caffeine evokes oscillations of the membrane potential (MP) with the amplitude of about 40 mV. The frequency of oscillations, on the crest of which action potentials (AP) arise, varied from 0.2 to 0.5 sec1.

Stable Potential Oscillation of Lipid Membrane Supported by a Micropore
Japanese Journal of Applied Physics, 1991A rhythmic, sustained, stable potential oscillation was reproducibly observed for a lipid membrane supported by a micropore of a thin membrane tip micropipette. Amplitude and period of the oscillation voltage was controlled by changing the pore diameter. The relationship between oscillation period and pore diameter when the pore diameter was below

Membrane potential oscillations underlying firing patterns in neocortical neurons
Neuroscience, 1994Membrane potential oscillations were studied in slices of rat somatosensory cortex maintained in vitro, using intracellular recordings from cells in layers 2/3 and 5. The cells were classified according to their firing patterns during long (0.8-1 s) depolarizing current steps. Subthreshold voltage oscillations were revealed by depolarizing the membrane

Oscillating Streaming Potential and Electro-osmosis of Multilayer Membranes
The Journal of Physical Chemistry B, 2004Artificial membranes consist of multilayers that have different physical or chemical properties. They are often considered as an equivalent single-layer membrane without taking into account the detail inside. Based on the Debye−Huckel approximation, we have provided analytical solutions of oscillating electrokinetic flow in multilayer membranes.

Standing wave oscillations in axon membranes and the action potential
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1997Abstract A standing wave description of dispersed colloidal particles of cubic lipid-water phases was recently introduced and extended to include cell membranes. Standing wave oscillations of the bilayer is a direct consequence of periodic curvature (two-dimensional crystallinity), with curvature and elastic rigidity controlling frequency, amplitude ...

Membrane potential dependence of potential oscillation induced by cevadine in striated muscle.
Acta physiologica Academiae Scientiarum Hungaricae, 1982The dependence of the membrane potential oscillation induced by cevadine on the actual transmembrane potential was studied in the frog sartorius muscle. 1. If the membrane potential oscillation is recorded for hours, its amplitude is seen to decrease slowly and smoothly and the membrane potential measured during the resting period among the waves of ...
