Abstract Background and Purpose The neural mechanisms underlying effects of acute stress on memory are poorly understood. We demonstrated previously that acute stress produces identical spatial memory deficits in male and female mice but through distinct molecular mechanisms, with females exhibiting up‐regulation of N‐methyl‐D‐aspartate (NMDA) receptor

Extrasynaptic localization of GABA in the developing mouse cerebellum [PDF]
In the adult brain, gamma-amino butyric acid (GABA) is synaptically released and mediates inhibitory transmission. Recent studies have revealed that GABA is a trophic factor for brain development. To reveal the distribution of GABA and its secretion mechanisms during brain development, we investigated the immunohistochemical localization of two ...

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

The Contribution of Extrasynaptic Signaling to Cerebellar Information Processing [PDF]
The diversity of synapses within the simple modular structure of the cerebellum has been crucial for study of the phasic extrasynaptic signaling by fast neurotransmitters collectively referred to as "spillover." Additionally, the accessibility of cerebellar components for in vivo recordings and their recruitment by simple behaviors or sensory stimuli ...

A microRNA signature of toxic extrasynaptic N-methyl-D-aspartate (NMDA) receptor signaling
The cellular consequences of N-Methyl-D-Aspartate receptor (NMDAR) stimulation depend on the receptors’ subcellular localization. Synaptic NMDARs promote plasticity and survival whereas extrasynaptic NMDARs mediate excitotoxicity and contribute to cell ...

Extrasynaptic GABA(A) receptors and tonic inhibition in rat auditory thalamus. [PDF]
Neural inhibition plays an important role in auditory processing and attentional gating. Extrasynaptic GABA(A) receptors (GABA(A)R), containing α(4)and δ GABA(A)R subunits, are thought to be activated by GABA spillover outside of the synapse following ...

Abstract Alzheimer's disease (AD) is a neurodegenerative condition marked by cognitive decline and synaptic issues. Recent studies show primary cilia (PCs), sensory organelles present on the surface of most mammalian cells, act as a critical regulators of brain homeostasis and signaling.

Astrocytes and extracellular matrix in extrasynaptic volume transmission [PDF]
Volume transmission is a form of intercellular communication that does not require synapses; it is based on the diffusion of neuroactive substances across the brain extracellular space (ECS) and their binding to extrasynaptic high-affinity receptors on neurons or glia.

The monocyclic sesquiterpene α‐humulene elicited a significant anxiolytic‐like behavior in adult zebrafish and no observable acute toxicity. Pharmacological dissection suggested that this effect is independent of the benzodiazepine (BZD) binding site on the gamma‐aminobutyric acid (GABA) type A receptor (GABAAR), but it depends on the serotonin type 3 ...

Extrasynaptic GABAA receptors in the crosshairs of hormones and ethanol [PDF]
Gamma-aminobutyric acid (GABA) is the main chemical inhibitory neurotransmitter in the brain. In the central nervous system (CNS) it acts on two distinct types of receptor: an ion channel, i.e., an "ionotropic" receptor permeable to Cl- and HCO3- (GABAA receptors) and a G-protein coupled "metabotropic" receptor that is linked to various effector ...
