GABA is short for Gamma-Aminobutyric Acid which is the most abundant inhibitory neurotransmitter in the brain.

GABA (gamma-aminobutyric acid) is a neurotransmitter that plays a central role in the functioning of the nervous system. It is involved in a number of important processes, including regulation of muscle tone, sleep, anxiety, and mood.

In the context of psychology, GABA is of particular interest because it is involved in the regulation of anxiety and stress. GABA is an inhibitory neurotransmitter, which means that it has a calming or relaxing effect on the nervous system. For example, when GABA levels are high, it can help to reduce anxiety and promote feelings of relaxation. When GABA levels are low, however, it can lead to increased anxiety and other psychological symptoms.

Examples of how GABA might be relevant in psychology include:
