Oscillations of membrane potential in L cells
The Journal of Membrane Biology, 1977The membrane potentials and resistances of L cells were measured using a standard electrophysiological technique. The values obtained in physiological media were around--15 mV and 37Momega, respectively. Almost all the large nondividing L cells (giant L cells) showed spontaneous oscillations of the membrane potential between around -15 and -40 mV ...

Oscillation of Membrane Potential in Immobilized DNA Membranes
The Journal of Physical Chemistry B, 2000Immobilized DNA membranes prepared by binding between DNA and poly(γ-methyl-l-glutamate) membranes having a cis-diaminedichloro platinum group-generated oscillation of the membrane potential under a concentration gradient of several salts at frequencies between 0 and 5 Hertz at pH 7.0, although nonmodified poly(γ-methyl-l-glutamate) membranes showed a ...

Modelling the interrelations between calcium oscillations and ER membrane potential oscillations
Biophysical Chemistry, 1997A refined electrochemical model accounting for intracellular calcium oscillations and their interrelations with oscillations of the potential difference across the membrane of the endoplasmic reticulum (ER) or other intracellular calcium stores is established.

Intrinsic membrane potential oscillations in hippocampal neurons in vitro
Brain Research, 1991Membrane potential oscillations (MPOs) of 2-10 Hz and up to 6 mV were found in almost all stable hippocampal CA1 and CA3 neurons in the in vitro slice preparation. MPOs were prominent for pyramidal cells but less pronounced in putative interneurons.

Dynamic Oscillations in the Membrane Potential of Pancreatic Islet Cells
Journal of Experimental Biology, 1979ABSTRACT Glucose and other metabolizable sugars which elicit insulin release from the β-cell of the pancreatic islet induce repetitive oscillations in the β-cell transmembrane potential. Upon each phasic depolarization are superimposed rapid fluctuations in potential, i.e.

Self-sustained oscillations of electric potential in a model membrane
Biophysical Chemistry, 1986A model membrane constructed from a Millipore filter, whose pores are filled with dioleyl phosphate molecules, exhibits a self-oscillation of the electric potential with a period of about a few seconds in the presence of a salt-concentration difference, pressure difference and/or electric current across the filter.

A membrane potential model with counterions for cytosolic calcium oscillations
Cell Calcium, 1994An initial model has been proposed to describe a mechanism for cytosolic calcium oscillations [Jafri MS. Vajda S. Pasik P. Gillo B. (1992) A membrane model for cytosolic calcium oscillations: a study using Xenopus oocytes. Biophys. J., 63, 235-246]. In this paper we extend our original model to include the effects of counterion movement into the ER in ...
