Absence seizures: Update on signaling mechanisms and networks
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Extrasynaptic site of action for γ-hydroxybutyrate [PDF]
Advances in pharmacology often result from identifying the mechanism of action of drugs found empirically to be biologically active (1). γ-Hydroxybutyric acid (GHB), also known as Fantasy, is a centrally active agent that has been used clinically and recreationally for nearly half a century.

GABA potency at GABAA receptors found in synaptic and extrasynaptic zones
The potency of GABA is vitally important for its primary role in activating GABAA receptors and acting as an inhibitory neurotransmitter. Although numerous laboratories have presented information, directly or indirectly, on GABA potency, it is often ...

Abstract Background and Aims The subjective experience of drug craving is characterized by an overwhelming urge to consume substances. Due to strong validity and ease of use, self‐report measures are widely employed to assess substance‐related motivational dynamics.

Abstract Epilepsy affects approximately 1% of the population worldwide, and although medications are effective in the majority of cases, seizures persist in approximately 30% of patients. Despite the effort to develop new antiseizure drugs, the rate of pharmacoresistance in patients has not diminished over the past 3 decades. There is thus a real unmet

Abstract Cocaine‐ and amphetamine‐regulated transcript (CART) is produced in several brain regions including the hypothalamus where it is made in cells that also produce melanin‐concentrating hormone (MCH). CART‐expressing MCH cells densely innervate the lateral septum (LS), which integrates food‐ and mood‐related behaviours.

Presynaptic and extrasynaptic regulation of posterior nucleus of thalamus [PDF]
The posterior nucleus of thalamus (PO) is a higher-order nucleus involved in sensorimotor processing, including nociception. An important characteristic of PO is its wide range of activity profiles that vary across states of arousal, thought to underlie differences in somatosensory perception subject to attention and degree of consciousness ...

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 ...

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 ...

Rapid homeostatic downregulation of LTP by extrasynaptic GluN2B receptors [PDF]
Although the activation of extrasynaptic GluN2B-containing N-methyl-d-aspartate (NMDA) receptors has been implicated in neurodegenerative diseases, such as Alzheimer’s and Huntington’s disease, their physiological function remains unknown. In this study, we found that extrasynaptic GluN2B receptors play a homeostatic role by antagonizing long-term ...
