TLDR
This article concludes a series of papers concerned with the flow of electric current through the surface membrane of a giant nerve fibre by putting them into mathematical form and showing that they will account for conduction and excitation in quantitative terms.
Abstract
This article concludes a series of papers concerned with the flow of electric current through the surface membrane of a giant nerve fibre (Hodgkinet al, 1952,J Physiol116, 424–448; Hodgkin and Huxley, 1952,J Physiol116, 449–566) Its general object is to discuss the results of the preceding papers (Section 1), to put them into mathematical form (Section 2) and to show that they will account for conduction and excitation in quantitative terms (Sections 3–6)

Strategy for rapid immobilization of prey by a fish-hunting marine snail

TL;DR: The purple cone, Conus purpurascens, uses two parallel physiological mechanisms requiring multiple neurotoxins to immobilize fish rapidly: neuromuscular block1, and excitotoxic shock.
Journal ArticleDOI

Action potentials and membrane currents in the human node of Ranvier

TL;DR: Action potentials and membrane currents were recorded in single human myelinated nerve fibres under current- and voltage-clamp conditions at room temperature and a mathematical model based on the Frankenhaeuser-Huxley equations was derived.
Journal ArticleDOI

Reconstruction of the action potential of frog sartorius muscle.

TL;DR: Propagated action potentials of striated muscle are calculated using an equivalent circuit that represents the transverse tubular system as a radial cable of sixteen elements.

Structure of the Nav1.4-β1 complex from electric Eel

TL;DR: Structural comparison with closed NavPaS shows that the outward transfer of gating charges is coupled to the iris-like pore domain dilation through intricate force transmissions involving multiple channel segments, suggesting a potential allosteric blocking mechanism for fast inactivation.
Journal ArticleDOI

Injection of digitally synthesized synaptic conductance transients to measure the integrative properties of neurons.

TL;DR: Cellular responses to synthetic conductance transients modelled on the fast (non-N-methyl-D-aspartate) phase of the glutamatergic postsynaptic potential were measured in cultured rat hippocampal neurons to allow quantitative measurement of the processing of synaptic inputs.

Potential, impedance, and rectification in membranes

TL;DR: A theoretical picture has been presented based on the use of the general kinetic equations for ion motion under the influence of diffusion and electrical forces and on a consideration of possible membrane structures that shows qualitative agreement with the rectification properties and very good agreementwith the membrane potential data.

Currents carried by sodium and potassium ions through the membrane of the giant axon of Loligo

TL;DR: The identity of the ions which carry the various phases of the membrane current is chiefly concerned with sodium ions, since there is much evidence that the rising phase of the action potential is caused by the entry of these ions.
Journal ArticleDOI

Measurement of current-voltage relations in the membrane of the giant axon of Loligo.

TL;DR: The importance of ionic movements in excitable tissues has been emphasized by a number of recent experiments which are consistent with the theory that nervous conduction depends on a specific increase in permeability which allows sodium ions to move from the more concentrated solution outside a nerve fibre to the more dilute solution inside it.

The dual effect of membrane potential on sodium conductance in the giant axon of Loligo

TL;DR: This paper contains a further account of the electrical properties of the giant axon of Loligo and deals with the 'inactivation' process which gradually reduces sodium permeability after it has undergone the initial rise associated with depolarization.
