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)

In Vitro excitation of purified membrane fragments by cholinergic agonists : I. Pharmalogical properties of the excitable membrane fragments.

TL;DR: The dose-response curve and the binding curve superimpose almost exactly; in other words, the “apparent” affinity of Deca coincides with its “real’ affinity.

Structural basis for gating charge movement in the voltage sensor of a sodium channel

TL;DR: High-resolution structural models of resting, intermediate, and activated states of the voltage-sensing domain of the bacterial sodium channel NaChBac are constructed using the Rosetta modeling method, crystal structures of related channels, and experimental data showing state-dependent interactions between the gating charge-carrying arginines in the S4 segment and negatively charged residues in neighboring transmembrane segments.

Patient-specific electromechanical models of the heart for the prediction of pacing acute effects in CRT: A preliminary clinical validation

TL;DR: How the personalisation of an electromechanical model of the myocardium can predict the acute haemodynamic changes associated with CRT is presented, demonstrating the potential of physiological models personalised from images and electrophysiology signals to improve patient selection and plan CRT.

Neuromorphic analogue vlsi

TL;DR: The significance of neuromorphic systems is that they offer a method of exploring neural computation in a medium whose physical behavior is analogous to that of biological nervous systems and that operates in real time irrespective of size.

Modeling stability in neuron and network function: the role of activity in homeostasis.

TL;DR: It is shown that similar neuronal and network outputs can be produced by a number of different combinations of ion channels and synapse strengths, which suggests that individual neurons of the same class may each have found an acceptable solution to a genetically determined pattern of activity.

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.

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.
