A distinction is often made between classical small-molecule neurotransmitters, including glutamate, GABA, glycine ... but it does not specify mechanism and, therefore, also extends to gaseous ...

A study published today in Current Biology finds that children and adults have different concentrations of a key brain messenger called gamma-aminobutyric acid or GABA. This messenger stabilizes ...

CryoEM structures show GABA-A receptors with GABA and modulators. Inhibitors constrict the ion channel via allosteric mechanisms. Benzodiazepines help GABA twist it, opening it. Researchers led by ...
