GABA, or gamma-aminobutyric acid, is the primary inhibitory neurotransmitter in the brain. Its main function is to reduce synaptic activity, which leads to a calming effect on the neuronal networks. This action is particularly significant in the context of anxiety regulation, as enhanced GABAergic activity helps to counteract the excitatory signals that can lead to heightened anxiety and panic.

The relationship between GABA and anxiety is well-documented. Low levels of GABA have been associated with increased anxiety levels, while medications that enhance GABA activity, such as benzodiazepines, are commonly prescribed to help alleviate anxiety symptoms. By inhibiting excessive neuronal firing, GABA fosters a sense of relaxation and stability, making it essential for maintaining emotional balance and reducing anxiety.

In contrast, the other neurotransmitters have different roles. Serotonin is linked to mood regulation, but its effects on anxiety are complex and not solely inhibitory. Acetylcholine primarily plays a role in excitatory processes, such as muscle activation and cognitive functions. Glutamate is the main excitatory neurotransmitter in the brain and is not associated with reducing synaptic activity; rather, it can heighten neuronal excitability. Therefore, GABA stands out as the
