2. Four Major Systems of Interest:Classifying on the Basis of the Major Neurotransmitter of Each Noradrenergic: Norepinephrine (NE) is the neurotransmitter. The locus coeruleus synthesizes and distributes the most.
Serotonergic: Serotonin (5-HT) is the neurotransmitter. Synthesized in a series of raphe nuclei.
Dopaminergic: Dopamine (DA) is the neurotransmitter. Synthesized in the ventral tegmental area and the substantia nigra.
Cholinergic: Acetylcholine (ACh) is the neurotransmitter. Synthesized in the laterodorsal and peduncular pontine tegmental nuclei
