Abstract
Stress responses activate protective mechanisms to achieve homeostasis, but they can be detrimental when such responses become maladaptive. Anxiety relates to risk assessment of a potential threat and involves uncertainty regarding the anticipation of a threatening situation and it dampers quality of life. Gamma-Aminobutyric Acid (GABA) is the major inhibitory system in the central nervous system and plays a key role in the regulation of neuronal transmission in the brain, affecting many physiological and psychological processes. This mini-review aims to summarize key points concerned with the GABAergic transmission and basic aspects related to the GABAergic system in anxiety.
