What is GABA in Brain?

Gamma-Aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the brain. It blocks, or inhibits, certain brain signals and decreases activity in your nervous system. The brain’s hypothalamus contains one of the highest amounts of GABA receptors. The hypothalamus works to maintain homeostasis in your body by controlling your pituitary gland and nervous system to regulate sleep, appetite, body temperature, and HPA-axis function.
