Gaba Definition
GABA (gamma aminobutyric acid) is a non-essential amino
acid found 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.
GABA or gamma-aminobutyric acid, discovered in 1950, is
the most important and widespread inhibitory neurotransmitter in
the brain. Excitation in the brain must be balanced with
inhibition. Too much excitation can lead to restlessness,
irritability, insomnia, and even seizures. GABA is able to
induce relaxation, analgesia, and sleep. Barbiturates and
benzodiazepines are known to stimulate GABA receptors, and hence
induce relaxation. Several neurological disorders, such as
epilepsy, sleep disorders, and Parkinson's disease are affected
by this neurotransmitter.
