GABA? Do not fully understand function

[nathhan.]

Hey does anybody know a detailed description of the function of gaba, the neurotransmitter?

[playsimme]

GABA is an inhibitory neurotransmitter - meaning that it's a neurotransmitter that promotes relaxation and prevents over arousal of the neurons in the brain by counterbalancing the excitaratory neurotransmitters (preventing them from firing). So it's proposed that one with LOW levels of GABA causes over arousal in the brain - as there's nothing to properly counterbalance the excitaratory neurotransmitters. So that in mind, it's proposed that this over arousal due to low GABA with nothing to balance it causes one to become heightened in anxiety - leading to the formation of a phobia.
Hope that was clear

It inhibits post-synaptic neuron from firing, and thus decreasing arousal levels. And everything else is explained by ^ =)

Please note that these are all contributing factors

There's no cause effect relationship such as LOW GABA = PHOBIA.
