Modulation of reconstructed peptidergic synapses and electrical synapses by general anaesthetics
Toxicology Letters, 19981. 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.

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

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 ...

Artificial electrical synapses in oscillatory networks
Journal of Neurophysiology, 19921. We use an electronic circuit to artificially electrically couple neurons. 2. Strengthening the coupling between an oscillating neuron and a hyperpolarized, passive neuron can either increase or decrease the frequency of the oscillator depending on the properties of the oscillator. 3.

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 Combined Effects of Inhibitory and Electrical Synapses in Synchrony
Neural Computation, 2005Recent experimental results have shown that GABAergic interneurons in the central nervous system are frequently connected via electrical synapses. Hence, depending on the area or the subpopulation, interneurons interact via inhibitory synapses or electrical synapses alone or via both types of interactions. The theoretical work presented here addresses

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 ...
