Neurotransmitter Pathways in the Brain
Neurotransmitters, the chemicals released by nerve cells at the neural synapses, are an important key to how emotions may be regulated in your brain. They are the chemicals that convey information between nerve cells and are known to follow predictable paths. About 50 neurotransmitters have been identified. Researchers have discovered associations between depression and the neurotransmitter gamma-aminobutyric acid (GABA). GABA activity can be studied by observing the known brain areas where it is present.
