The double dipole model of theta rhythm generation: Simulation of laminar field potential profiles in dorsal hippocampus of the rat [PDF]
A set of compartmental models of CA1 pyramidal, granular and polymorph cells of the dorsal hippocampus have been used to simulate membrane potentials generated by synaptic activation at various levels along these cells.

Analogue modulation of back-propagating action potentials enables dendritic hybrid signalling
‘Analogue’ modulation by somatic membrane potentials can modify ‘digital’ axonal action potentials. Here, the authors show that analogue modulation can occur in back-propagating dendritic action potentials and calcium signals, leading to signal ...

Particle transport across a channel via an oscillating potential [PDF]
Membrane protein transporters alternate their substrate-binding sites between the extracellular and cytosolic side of the membrane according to the alternating access mechanism.

Modulation of neural cell membrane conductance by the herbal anxiolytic and antiepileptic drug aswal [PDF]
To evaluate the effects of aswal on ionic fluxes and neuronal excitation, we performed extracellular and whole cell patch clamp recordings on CA1 pyramidal neurons of guinea pigs and Long-Evans rats.

Probing the membrane potential of living cells by dielectric spectroscopy [PDF]
In this paper we demonstrate a quantitative way to measure the membrane potential of live cells by dielectric spectroscopy. We also show that the values of the membrane potential obtained using our technique are in good agreement with those obtained using traditional methods-voltage sensitive dyes.

Feedback-controlled solute transport through chemo-responsive polymer membranes [PDF]
Polymer membranes are typically assumed to be inert and nonresponsive to the flux and density of the permeating particles in transport processes. Here, we study theoretically the consequences of membrane responsiveness and feedback on the steady-state force--flux relations and membrane permeability using a nonlinear-feedback solution-diffusion model of

Lateral phase separation of confined membranes [PDF]
We consider membranes interacting via short, intermediate and long stickers. The effects of the intermediate stickers on the lateral phase separation of the membranes are studied via mean-field approximation. The critical potential depth of the stickers increases in the presence of the intermediate sticker.

MEMBRANE POTENTIALS AND CATAPHORETIC POTENTIALS OF PROTEINS [PDF]
1. It has been shown in preceding publications that the membrane potentials of protein solutions or gels are determined by differences in the concentration of a common ion (e.g. hydrogen ion) inside a protein solution or protein gel and an outside aqueous solution free from protein, and that the membrane potentials can be calculated with a good degree ...

Effect of channel block on the spiking activity of excitable membranes in a stochastic Hodgkin-Huxley model [PDF]
The influence of intrinsic channel noise on the spontaneous spiking activity of poisoned excitable membrane patches is studied by use of a stochastic generalization of the Hodgkin-Huxley model.

Effective zero-thickness model for a conductive membrane driven by an electric field [PDF]
The behavior of a conductive membrane in a static (DC) electric field is investigated theoretically. An effective zero-thickness model is constructed based on a Robin-type boundary condition for the electric potential at the membrane, originally developed for electrochemical systems.
