GABA Receptors

Meaning

GABA receptors are a class of ligand-gated ion channels and G-protein coupled receptors found in the central nervous system that respond to the neurotransmitter Gamma-Aminobutyric Acid (GABA). GABA is the principal inhibitory neurotransmitter in the mature brain, and its receptors play a critical role in reducing neuronal excitability, thereby promoting relaxation, sedation, and anxiety reduction. These receptors are essential modulators of sleep cycles and emotional regulation.
