Gap Junctions as Electrical Synapses
Journal of Neurocytology, 1996Gap 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.

On a Method of Mathematical Modeling of Electrical Synapses
Differential Equations, 2022This 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 ...

Modification of Electrical Synapses
Science, 2005The 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, 1992This 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, 2002The 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 ...

The memristor as an electric synapse - synchronization phenomena
2011 17th International Conference on Digital Signal Processing (DSP), 2011Today 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

Electrical Synapses – Gap Junctions in the Brain
2006In the nervous system, interneuronal communication can occur via indirect or direct transmission. The mode of indirect communication involves chemical synapses, in which transmitters are released into the extracellular space to subsequently bind to the postsynaptic cell membrane.

The Synapse: From Electrical to Chemical Transmission
Annual Review of Neuroscience, 1982The controversy as to whether synaptic transmission in the central nervous system is electrical or chemical played a key role in the origin of modern neuroscience, and I shall attempt to give it a historical perspective. Almost 100 years ago (1886-1890) it was recognized by several neuroanatomists, including His, Forel, and Ramon y Cajal, that nerve ...

Plasticity at electrical synapses
2013Trafficking of transmitter receptors to maintain and modify strength of chemical synapses has been characterized extensively. However, trafficking of gap junction components at electrical synapses is little known, although turnover time of connexin gap junctions in, e.g., heart, liver, and recombinant systems, is a few hours.
