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.

Artificial electrical synapses in oscillatory networks
Journal of Neurophysiology, 1992 1. 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.

Interaction of anaesthetics with electrical synapses
Nature, 1980Studies 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 Combined Effects of Inhibitory and Electrical Synapses in Synchrony
Neural Computation, 2005 Recent 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

Electrical synapses, a personal perspective (or history)
Brain Research Reviews, 2000Gap junctions are the morphological substrate of one class of electrical synapse. This memoir records the author's involvement in the development of our knowledge of the physiology and ultrastructure of electrical synapses. The answer to whether neurotransmission is electrical or chemical is either.

Anatomical distribution and functional roles of electrical synapses in Drosophila
Current Biology, 2022 Electrical synapses are present in almost all organisms that have a nervous system. However, their brain-wide expression patterns and the full range of contributions to neural function are unknown in most species.

On the location of electrical synapses
Developmental Cell, 2021Location is of critical functional relevance for synapses, including electrical synapses, which are a form of neuronal communication mediated by cell-cell channels. In this issue of Developmental Cell, Palumbos et al. identify a mechanism that supports the localization and function of electrical synapses with subcellular specificity.

Exact Mean-Field Theory Explains the Dual Role of Electrical Synapses in Collective Synchronization
Physical Review Letters, 2020 Electrical synapses play a major role in setting up neuronal synchronization, but the precise mechanisms whereby these synapses contribute to synchrony are subtle and remain elusive.

Exact firing rate model reveals the differential effects of chemical versus electrical synapses in spiking networks [PDF]
Physical Review E, 2019 Chemical and electrical synapses shape the dynamics of neuronal networks. Numerous theoretical studies have investigated how each of these types of synapses contributes to the generation of neuronal oscillations, but their combined effect is less ...
