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)

Memristor, Hodgkin-Huxley, and edge of chaos.

TL;DR: This tutorial shows that memristor span a much broader vista of complex phenomena and potential applications in many fields, including neurobiology, and presents toy memristors that can mimic the classic habituation and LTP learning phenomena.

Structure of potassium channels

TL;DR: The structure of various kinds of potassium channels are discussed, including the potassium channel with the pore-forming domain only (KcsA), voltage-gated, inwardly rectifying, tandem pore domain, and ligand- gated ones.
Journal ArticleDOI

Firing-rate response of linear and nonlinear integrate-and-fire neurons to modulated current-based and conductance-based synaptic drive.

TL;DR: It is demonstrated that a rather simple numerical method can be used to obtain the steady-state and dynamic response for both linear and nonlinear models to parameter modulation in the presence of current-based or conductance-based synaptic fluctuations.

Detecting and estimating signals in noisy cable structures, I: neuronal noise sources

TL;DR: A theoretical analysis of the information loss of a synaptic signal propagating along a linear, one-dimensional, weakly active cable due to neuronal noise sources along the way is carried out, using both a signal reconstruction and a signal detection paradigm.
Journal ArticleDOI

Dihydropyridine-sensitive and omega-conotoxin-sensitive calcium channels in a mammalian neuroblastoma-glioma cell line.

TL;DR: The results indicate that two classes of Ca2+ channels contribute to the HVA currents of this cell line, and the DHP‐sensitive channel is more apt to generate Ca 2+ spikes and Ca2- plateau potentials than the omega CgTX‐ sensitive channel.

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.
