What does the neurotransmitter GABA do?

Neurotransmitter GABA is distributed very widely in the neurons of the cortex. Every day, our brain maintains a balance between chemicals that push its cells to fire and opposing chemicals that pull its cells back toward inactivity. Two of the most common neurochemicals are glutamate and GABA and both are a neurotransmitter. Neurons in every region of the brain use GABA to fine-tune neurotransmission.
