GABA (Gamma-Aminobutyric Acid)
⤢ 3D
GABA is the brain’s principal inhibitory neurotransmitter, counterbalancing excitatory glutamate to keep neural activity stable. By opening chloride channels it quiets neurons, producing calming, anti-anxiety, and sedative effects — the mechanism enhanced by benzodiazepines, alcohol, and many sleep aids. Adequate GABAergic tone is essential for preventing seizures and regulating anxiety, sleep, and muscle tone.
Too little may be associated with
Anxiety, seizures, insomnia
Too much may be associated with
Excessive sedation, impaired cognition
