Detailed explanation-1: -Serotonin is an inhibitory neurotransmitter. Serotonin helps regulate mood, sleep patterns, sexuality, anxiety, appetite and pain.
Detailed explanation-2: -GABA (-aminobutyric acid) GABA is a main inhibitory neurotransmitter. It reduces the activity in the central nervous system and blocks certain signals from your brain. Without GABA, your brain would be “on” all the time. You need GABA to produce a calming effect that slows you down.
Detailed explanation-3: -GABA-B receptors are present as autoreceptors that inhibit GABA release or heteroreceptors that reduce the release of glutamate, norepinephrine, serotonin, or dopamine.
Detailed explanation-4: -Gamma-aminobutyric acid (GABA) is the central nervous system’s main inhibitor . It is a mood regulator, and experts have linked low levels of it with anxiety, depression, and schizophrenia. Benzodiazepines, or “benzos, ‘’ are drugs that can treat anxiety. They work by increasing the action of GABA.
