GABA (gamma aminobutyric acid) is a non-essential amino acidfound mainly in the human brain and eyes. It is considered an inhibitory neurotransmitter, which means it regulates brain and nerve cell activity by inhibiting the number of neurons firing in the brain. GABA is referred to as the brain's natural calming agent. By inhibiting over-stimulation of the brain, GABA may help promote relaxation and ease nervous tension. Provides only the naturally occurring L-form as found in food and in the body.
In vertebrates, GABA acts at inhibitory synapses in the brain. GABA acts by binding to specific receptors in the plasma membrane of both pre- and postsynaptic neurons. This binding causes the opening of ion channels to allow either the flow of negatively-charged chloride ions into the cell or positively-charged potassium ions out of the cell. This will typically result in a negative change in the transmembrane potential, usually causing hyperpolarization.
Three general classes of GABA receptor are known. These include GABAA and GABAC ionotropic receptors, which are ion channels themselves, and GABAB metabotropic receptors, which are G protein-coupled receptors that open ion channels via intermediaries (G proteins).
Neurons that produce GABA as their output are called GABAergic neurons, and have chiefly inhibitory action at receptors in the vertebrate. Medium Spiny Cells are a typical example of inhibitory CNS GABAergic cells. GABA exhibits excitatory actions in insects, mediating muscle activation at synapses between nerves and muscle cells and also the stimulation of certain glands. GABA has also been shown to have excitatory roles in the vertebratemost notably in the developing cortex.
