Dopamine mediates diverse functions such as motivation, reward, attention, learning/memory and sleep/arousal. Recent studies using model organisms including the fruit fly, have elucidated various physiological functions of dopamine, and identified ...

An in vivo biosensor for neurotransmitter release and in situ receptor activity. [PDF]
Tools from molecular biology, combined with in vivo optical imaging techniques, provide new mechanisms for noninvasively observing brain processes. Current approaches primarily probe cell-based variables, such as cytosolic calcium or membrane potential ...

Modulation of the GABAergic pathway for the treatment of fragile X syndrome. [PDF]
Fragile X syndrome (FXS) is the most common genetic cause of intellectual disability and the most common single-gene cause of autism. It is caused by mutations on the fragile X mental retardation gene (FMR1) and lack of fragile X mental retardation ...

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 ...

Zuranolone: A case study in (regulatory) rush to judgement?
Abstract Sage, in collaboration with Biogen, submitted a new drug approval for zuranolone for postpartum depression (PPD) and major depressive disorder (MDD) in December 2022. In August 2023, the US Food and Drug Administration granted approval for PPD but denied approval for MDD.

Synaptic and Extrasynaptic Factors Governing Glutamatergic Retinal Waves [PDF]
In the few days prior to eye-opening in mice, the excitatory drive underlying waves switches from cholinergic to glutamatergic. Here, we describe the unique synaptic and spatiotemporal properties of waves generated by the retina's glutamatergic circuits. First, knockout mice lacking vesicular glutamate transporter type 1 do not have glutamatergic waves,

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

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.

A synaptic nidogen: developmental regulation and role of nidogen-2 at the neuromuscular junction [PDF]
Background: The skeletal neuromuscular junction is a useful model for elucidating mechanisms that regulate synaptogenesis. Developmentally important intercellular interactions at the neuromuscular junction are mediated by the synaptic portion of a basal ...
