Electrical synapses and their functional interactions with chemical synapses [PDF]

Nature Reviews Neuroscience, 2014
Brain function relies on the ability of neurons to communicate with each other. Interneuronal communication primarily takes place at synapses, where information from one neuron is rapidly conveyed to a second neuron. There are two main modalities of synaptic transmission: chemical and electrical. Far from functioning independently and serving unrelated

Modulation of reconstructed peptidergic synapses and electrical synapses by general anaesthetics

Toxicology Letters, 1998
1. The actions of clinically relevant concentrations of general anaesthetics on reconstructed peptidergic synapses and electrical synapses in the intact brain of the mollusc Lymnaea stagnalis (L.) are described. 2. At identified, reconstructed, FMRFamidergic synapses, chemical synaptic transmission is completely blocked in 2% halothane. 3.

On a Method of Mathematical Modeling of Electrical Synapses

Differential Equations, 2022
This paper introduces a new mathematical model of a neural network (of \(m\geq 2\) neurons) with electrical synapses. The model is a singularly perturbed system of delay differential equations of the form \[\dot{u}_j=\left[\lambda f\left(u_j(t-1)\right)+\sum_{\substack{s=1 \\ s \neq j}}^m d_{j, s} g\left(\frac{u_s}{u_j}\right)\right] u_j, \quad j=1 ...

Gap Junctions as Electrical Synapses

Journal of Neurocytology, 1996
Gap junctions are the morphological substrate of one class of electrical synapse. The history of the debate on electrical vs. chemical transmission is instructive. One lesson is that Occam's razor sometimes cuts too deep; the nervous system does its operations in a number of different ways and a unitarian approach can lead one astray.

Interaction of anaesthetics with electrical synapses

Nature, 1980
Studies of the interaction of anaesthetics with various preparations, from whole animals to organic solvents, have been continuing since Overton and Meyer found a correlation between anaesthetic potency and solubility in olive oil. Although the physiological basis of anaesthesia is far from clear, one popular hypothesis is that anaesthetics act ...

The memristor as an electric synapse - synchronization phenomena

2011 17th International Conference on Digital Signal Processing (DSP), 2011
Today many scientists see nonlinear science as the most important frontier for the fundamental understanding of Nature. Especially, the recent implementation of the memristor has led to the interpretation of phenomena not only in electronic devices but also in biological systems. Many research teams work on projects, which use memristor to simulate the

Modification of Electrical Synapses

Science, 2005
The brain has two main types of synapses, chemical and electrical. Electrical synapses represent a major form of communication between interneurons in the mammalian nervous system. They play an important role in synchronization of activity in local cell populations because their speed and reliability allow signals to spread across whole networks at a ...

Ultrastructure of electrical synapses: Review

Electron Microscopy Reviews, 1992
This article reviews studies providing information on the ultrastructure of electrical synapses. Although the review focuses on electron-microscopic investigations, its aim is to examine how the structure of an electrical synapse relates to its function.

On the search for the electrical synapse: a glimpse at the future

Cell and Tissue Research, 2002
The traditional concept of electrotonic synapses suggests that they synchronize outputs from coupled neurons and provide rapid impulse propagation between pre- and postsynaptic elements. These properties have provided an evolutionary advantage in certain behavioral repertoires, for example, in the rapid impulse propagation between axonal segments in ...
