Low GABA Levels. One of the main causes of sleep maintenance insomnia results from low levels of the brain chemical (neurotransmitter) called GABA. GABA is your main relaxing and tranquillising brain chemical.
GABA'S ROLE IN THE BRAIN. GABA is made in brain cells from glutamate, and functions as an inhibitory neurotransmitter  meaning that it blocks nerve impulses. Glutamate acts as an excitatory neurotransmitter and when bound to adjacent cells encourages them to fire and send a nerve impulse.
