Liquid Junction and Membrane Potentials of the Squid Giant Axon
The potential differences across the squid giant axon membrane, as measured with a series of microcapillary electrodes filled with concentrations of KCl from 0.03 to 3.0 M or sea water, are consistent with a constant membrane potential and the liquid junction potentials calculated by the Henderson equation. The best value for the mobility of an organic univalent ion, such as isethionate, leads ...
متن کاملLiquid junction potentials between electrolyte solutions in different solvents.
Many chemists are not familiar with the problem of the liquid junction potential (LJP) between electrolyte solutions in different solvents. Some even misunderstand it. Therefore, it seems worthwhile to write a review article on this subject. The LJP between electrolyte solutions in different solvents consists of three components: i.e., (a) a component related to electrolyte concentrations and i...
متن کاملOn the nature of liquid junction and membrane potentials.
Whenever a spatially inhomogeneous electrolyte, composed of ions with different mobilities, is allowed to diffuse, charge separation and an electric potential difference is created. Such potential differences across very thin membranes (e.g. biomembranes) are often interpreted using the steady state Goldman equation, which is usually derived by assuming a spatially constant electric field. Thro...
متن کاملMiniature Excitatory Junction Potentials
Neuromuscular transmission of excitation in invertebrates has been studied extensively by many investigators (cf. Bullock & Horridge, 1963). Miniature inhibitory junction potentials (m.i.j.p.s) and miniature excitatory junction potentials (m.e.j.p.s) could be recorded from the longitudinal layer of the somatic muscle in the earthworm. Field stimulation to the peripheral nerves elicited inhibito...
متن کاملLiquid-liquid phase transitions for soft-core attractive potentials.
Using event-driven molecular dynamics simulations, we study a three-dimensional one-component system of spherical particles interacting via a discontinuous potential combining a repulsive square soft core and an attractive square well. In the case of a narrow attractive well, it has been shown that this potential has two metastable gas-liquid critical points. Here we systematically investigate ...
