Adaptive neural information processing with dynamical electrical synapses
Frontiers in Computational Neuroscience, 2013 The present study investigates a potential computational role of dynamical electrical synapses in neural information process. Compared with chemical synapse, electrical synapse is more efficient in modulating the concerted activity of neurons.

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

Mixed synapses reconcile violations of the size principle in zebrafish spinal cord
eLife, 2022 Mixed electrical-chemical synapses potentially complicate electrophysiological interpretations of neuronal excitability and connectivity. Here, we disentangle the impact of mixed synapses within the spinal locomotor circuitry of larval zebrafish.

A Direct Comparison of Different Measures for the Strength of Electrical Synapses
Frontiers in Cellular Neuroscience, 2019 During the last decades it became increasingly evident that electrical synapses are capable of activity-dependent plasticity. However, measuring the actual strength of electrical transmission remains difficult.

The Variable Strength of Electrical Synapses [PDF]
Neuron, 2016 In contrast to chemical synapses, less is known regarding the determinants of the strength of electrical synapses. New evidence from Szoboszlay et al. (2016) shows that the number of gap junctions is the dominant factor underlying the strength of electrical coupling between cerebellar interneurons.

eLife, 2021 Gap junctions between neurons serve as electrical synapses, in addition to conducting metabolites and signaling molecules. During development, early-appearing gap junctions are thought to prefigure chemical synapses, which appear much later.

Anatomically detailed and large-scale simulations studying synapse loss and synchrony using NeuroBox
Frontiers in Neuroanatomy, 2016 The morphology of neurons and networks plays an important role in processing electrical and biochemical signals. Based on neuronal reconstructions, which are becoming abundantly available through databases such as NeuroMorpho.org, numerical simulations ...

Electrical Synapses: Rectification Demystified [PDF]
Current Biology, 2009 Some electrical synapses rectify - they pass current preferentially in one direction. A new study argues that rectifying junctions result when the two sides of the junction contribute hemichannels with different properties to the gap junction.
