Abstract figure legend With ageing and age‐related neurodegenerative diseases, the amount of GABA and GABAergic inhibition as well as the modulation (indicated by sine wave) of GABAergic inhibition is reduced, whereas excitation is increased. In many parts of the brain, this leads to a mismatch of facilitatory (green neurons) and inhibitory (red ...

Tetramethylenedisulfotetramine alters Ca²⁺ dynamics in cultured hippocampal neurons: mitigation by NMDA receptor blockade and GABA(A) receptor-positive modulation. [PDF]
Tetramethylenedisulfotetramine (TETS) is a potent convulsant that is considered a chemical threat agent. We characterized TETS as an activator of spontaneous Ca²⁺ oscillations and electrical burst discharges in mouse hippocampal neuronal cultures at 13 ...

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.

Phasic, nonsynaptic GABA-A receptor-mediated inhibition entrains thalamocortical oscillations. [PDF]
GABA-A receptors (GABA-ARs) are typically expressed at synaptic or nonsynaptic sites mediating phasic and tonic inhibition, respectively. These two forms of inhibition conjointly control various network oscillations.

ABSTRACT Non‐suicidal self‐injury (NSSI) is a complex and often misunderstood behavior linked to emotional dysregulation, trauma, and substance use. In this case report we present a 19‐year‐old female with a history of childhood trauma and substance use, who engaged in self‐injurious behavior as a coping mechanism to manage distress and maintain ...

Extrasynaptic GABAAReceptors: Form, Pharmacology, and Function [PDF]
GABA is the principal inhibitory neurotransmitter in the CNS and acts via GABAAand GABABreceptors. Recently, a novel form of GABAAreceptor-mediated inhibition, termed “tonic” inhibition, has been described. Whereas synaptic GABAAreceptors underlie classical “phasic” GABAAreceptor-mediated inhibition (inhibitory postsynaptic currents), tonic ...

GABAA receptors (γ-aminobutyric acid-gated receptors type A; GABAARs), the major structural and functional postsynaptic components of inhibitory synapses in the mammalian brain, belong to a family of GABA-gated Cl−/HCO3− ion channels.

Reduction in Phencyclidine Induced Sensorimotor Gating Deficits in the Rat Following Increased System Xc − Activity in the Medial Prefrontal Cortex [PDF]
Rationale: Aspects of schizophrenia, including deficits in sensorimotor gating, have been linked to glutamate dysfunction and/or oxidative stress in the prefrontal cortex. System xc −, a cystine–glutamate antiporter, is a poorly understood mechanism that

Amyloid Beta in Alzheimer's Disease: Mechanisms, Biomarker Potential, and Therapeutic Targets
The limited clinical efficacy of anti‐Aβ antibodies has challenged the Aβ hypothesis, compelling the integration of key mechanisms—including neuroinflammation, mitochondrial dysfunction, oxidative stress, and post‐translational modifications of Aβ—into a revised model of Alzheimer's disease.
