TLDR
The action potential of the squid giant axon is formed by just two voltage-dependent conductances in the cell membrane, yet mammalian central neurons typically express more than a dozen different types of voltage- dependent ion channels.
Abstract
The action potential of the squid giant axon is formed by just two voltage- dependent conductances in the cell membrane, yet mammalian central neurons typically express more than a dozen different types of voltage-dependent ion channels. This rich repertoire of channels allows neurons to encode information by generating action potentials with a wide range of shapes, frequencies and patterns. Recent work offers an increasingly detailed understanding of how the expression of particular channel types underlies the remarkably diverse firing behaviour of various types of neurons.

Dendritic Excitability and Synaptic Plasticity

TL;DR: It is argued that the location of synapses in the dendritic tree, and the type of dendrite excitability associated with each synapse, play decisive roles in determining the plastic properties of that synapse.

Genetically encoded indicators of neuronal activity

TL;DR: This review describes and assess different classes of fluorescent protein indicators of neural activity and focuses on how indicator characteristics relate to their use in living animals and on likely areas of future progress.

Unravelling cerebellar pathways with high temporal precision targeting motor and extensive sensory and parietal networks

TL;DR: By electrically stimulating the cerebellum output and imaging responses with functional magnetic resonance imaging, evoked blood oxygen level-dependant activity is observed not only in the classical cerebellar projection target, the primary motor cortex, but also in a number of additional areas in insular, parietal and occipital cortex, including sensory cortical representations.

A quantitative description of membrane current and its application to conduction and excitation in nerve

TL;DR: 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.

Ion Channels of Excitable Membranes

Bertil Hille
TL;DR: The superfamily of voltage-gated channels was studied in this paper, where a classical biophysics of the squid giant axon was discussed. But the superfamily was not considered in this paper.

Ion Channels in Excitable Membranes

TL;DR: The action potential is triggered when the membrane potential, which was at the resting level, depolarizes and reaches the threshold of excitation, which triggers the action potential.

The intrinsic electrophysiological properties of mammalian neurons: insights into central nervous system function.

TL;DR: It is proposed that the autorhythmic electrical properties of central neurons and their connectivity form the basis for an intrinsic functional coordinate system that provides internal context to sensory input.

Comparative electrophysiology of pyramidal and sparsely spiny stellate neurons of the neocortex.

TL;DR: Slices of sensorimotor and anterior cingulate cortex from guinea pigs were maintained in vitro and bathed in a normal physiological medium, observing three distinct neuronal classes of electrophysiological behavior; these were regular spiking, bursting, and fast spiking.
