Biogenic amines {dopamine}| (DA) are in hypothalamic arcuate nucleus, midbrain nigrostriatal, and ventral midbrain. Dopamine affects reward processing. It initiates and maintains anticipation behavior, novelty, attention, and action selection. Dopamine interacts with amine and choline modulators.
Dopaminergic neurons use adrenaline or epinephrine, noradrenaline or norepinephrine, dopamine, or serotonin. Dopaminergic neurons can make highly branched networks with small-diameter ascending and descending fibers, low frequency potentials, and slow conduction velocities.
