GABA Gamma-Aminobutyric Acid

GABA (gamma-aminobutyric acid) is a type of neurotransmitter, which is a chemical messenger that transmits signals between nerve cells in the brain. It is considered to be the primary inhibitory neurotransmitter in the central nervous system (CNS), meaning it reduces the activity of nerve cells in the brain and spinal cord.

GABA plays a crucial role in regulating various brain functions, including relaxation, sleep, and feelings of calmness. It helps to counterbalance the effects of excitatory neurotransmitters, such as glutamate, by inhibiting or reducing the firing of nerve cells in the brain.

Imbalances or deficiencies in GABA levels have been associated with several neurological and psychiatric conditions, including anxiety disorders, epilepsy, insomnia, and mood disorders. Consequently, medications that enhance GABA activity, known as GABAergic drugs, are often used to treat these conditions by increasing inhibitory effects and promoting relaxation.

Overall, GABA is an essential neurotransmitter that contributes to maintaining the balance and proper functioning of the brain by inhibiting excessive neuronal activity.
