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.

Nanoscale-targeted patch-clamp recordings of functional presynaptic ion channels [PDF]

, 2013
Important modulatory roles have been attributed to presynaptic NMDA receptors (NMDARs) located on cerebellar interneuron terminals. Evidence supporting a presynaptic location includes an increase in the frequency of mini events following the application ...

Habituation of the C-start response in larval zebrafish exhibits several distinct phases and sensitivity to NMDA receptor blockade. [PDF]

, 2011
The zebrafish larva has been a valuable model system for genetic and molecular studies of development. More recently, biologists have begun to exploit the surprisingly rich behavioral repertoire of zebrafish larvae to investigate behavior.

The ever-changing electrical synapse [PDF]

Current Opinion in Neurobiology, 2014
A wealth of research has revealed that electrical synapses in the central nervous system exhibit a high degree of plasticity. Several recent studies, particularly in the retina and inferior olive, highlight this plasticity. Three classes of mechanisms can alter electrical coupling over time courses ranging from milliseconds to days. Changes of membrane

Hemichannel composition and electrical synaptic transmission: molecular diversity and its implications for electrical rectification.

Frontiers in Cellular Neuroscience, 2014
Unapposed hemichannels formed by oligomerized hexamers of gap junction proteins are now known to be involved in various cellular processes under both physiological and pathological conditions. On the other hand, less is known regarding how disparities in

Asymmetry of an Intracellular Scaffold at Vertebrate Electrical Synapses. [PDF]

Curr Biol, 2017
Abstract Neuronal synaptic connections are electrical or chemical and together are essential to dynamically defining neural circuit function. While chemical synapses are well known for their biochemical complexity, electrical synapses are often viewed as comprised solely of neuronal gap junction channels that allow ...

Image informatics strategies for deciphering neuronal network connectivity [PDF]

, 2016
Brain function relies on an intricate network of highly dynamic neuronal connections that rewires dramatically under the impulse of various external cues and pathological conditions.

Connexin36 Expression in the Mammalian Retina: A Multiple-Species Comparison

Frontiers in Cellular Neuroscience, 2017
Much knowledge about interconnection of human retinal neurons is inferred from results on animal models. Likewise, there is a lack of information on human retinal electrical synapses/gap junctions (GJ).
