GABA / GABAergic

Also known as: GABA · gamma-aminobutyric acid · GABAergic

The brain’s main calming neurotransmitter; modulating GABA signalling is part of Selank’s anxiolytic research.

GABA (gamma-aminobutyric acid) is the primary inhibitory neurotransmitter in the brain — the main "calming" signal that balances excitatory activity. Systems that respond to it are described as GABAergic.

Influence on GABAergic and related signalling is part of the proposed mechanism behind the anxiolytic peptide Selank, which is studied for calm focus and stress resilience without the sedation of classical GABA drugs.
