Extrasynaptic Neurotransmission as a Way of Modulating Neuronal Functions [PDF]
Extrasynaptic neurotransmission allows neuronal communication at variable distances, based on the release and diffusion of chemical substances from the soma, axon, or dendrites of neurons, or after transmitter leak-out from the synaptic cleft (De-Miguel and Trueta, 2005; Fuxe et al., 2007).

Functional properties and pharmacology of extrasynaptic GABA-A receptors [PDF]
The “ambient” GABA that is present in the extracellular space surrounding all neurons of the brain is believed to be capable of persistently activating high‐affinity extrasynaptic GABA-A receptors to generate a tonic membrane conductance.

Synaptic versus extrasynaptic NMDA receptor signalling: implications for neurodegenerative disorders [PDF]
There is a long-standing paradox that NMDA (N-methyl-D-aspartate) receptors (NMDARs) can both promote neuronal health and kill neurons. Recent studies show that NMDAR-induced responses depend on the receptor location: stimulation of synaptic NMDARs ...

Pathophysiological power of improper tonic GABAA conductances in mature and immature models
High-affinity extrasynaptic gamma-aminobutyric acid A (GABAA) receptors are tonically activated by low and consistent levels of ambient GABA, mediating chronic inhibition against neuronal excitability (tonic inhibition) and the modulation of neural ...

Nanoscale Spatial Organization of ARC High‐ and Low‐Order Assemblies at Excitatory Synapses
ARC (Activity‐Regulated Cytoskeleton‐Associated protein) mediates synaptic plasticity by forming nanoscale assemblies in neurons. Using super‐resolution microscopy and time‐resolved anisotropy with targeted tagging, the study reveals low‐order ARC assemblies at synapses colocalizing with AMPARs, semi‐circular structures at endocytic zones, and 60–80 nm

Fast detection of extrasynaptic GABA with a whole-cell sniffer
Gamma-amino-butyric acid (GABA) is the main inhibitory transmitter of the brain. It operates by binding to specific receptors located both inside and outside synapses.

Background A subanesthetic dose of ketamine provides rapid and effective antidepressant effects, but the molecular mechanism remains elusive. It has been reported that overactivation of extrasynaptic GluN2B receptors is associated with the antidepressant

With the discovery that the acquisition of toxic features by extrasynaptic NMDA receptors (NMDARs) involves their physical interaction with the non-selective cation channel, TRPM4, it has become possible to develop a new pharmacological principle for ...

Pathophysiological role of extrasynaptic GABAA receptors in typical absence epilepsy [PDF]
GABA is the principal inhibitory neurotransmitter in the mammalian CNS. It acts via two classes of receptors, the GABAA, a ligand gated ion channel (ionotropic receptor) and the metabotropic G-protein coupled GABAB receptor.

Extrasynaptic NR2D-containing NMDARs are recruited to the synapse during LTP of NMDAR-EPSCs
Long-term potentiation of NMDA-receptor-mediated synaptic transmission (NMDAR-LTP) is a little-understood form of plasticity. In the present study, we investigated whether NMDAR-LTP in the dentate gyrus involves recruitment of extrasynaptic NMDARs ...
