1.58% of the population were Hispanic or Latino of any race. In the county, the population was spread out with 23.00% under the age of 18, 10.90% from 18 to 24, 26.40% from 25 to 44, 24.40% from 45 to 64, and 15.20% who were 65 years of age or older. The median age was 38 years.
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.NTRODUCTION: Gamma-Amino Butyric acid (GABA) is an amino acid which acts as a neurotransmitter in the central nervous system. It inhibits nerve transmission in the brain, calming nervous activity. As a supplement it is sold and promoted for these neurotransmitter effects as a natural tranquilizer.
Increasing GABA at the neuronal synapse inhibits the generation of the action potential of the neuron, thereby making it less likely to excite nearby neurons. A single neuron may have thousands of other neurons synapsing onto it. Some of these release activating (or depolarizing) neurotransmitters; others release inhibitory (or hyperpolarizing) neurotransmitters. GABA is the primary inhibitory neurotransmitter, which means it decreases the neuron's action potential. When the action potential drops below a certain level, known as the threshold potential, the neuron will not generate action potentials and thus not excite nearby neurons.
