Dopaminergic pathways

Dopaminergic pathways are neural pathways in the brain which transmit the neurotransmitter dopamine from one region of the brain to another.

The neurons of the dopaminergic pathways have axons which run the entire length of the pathway. The neurons' soma produces the enzymes that synthesize dopamine, and they are then transmitted via the projecting axons to their synaptic destinations, where most of the dopamine is produced. Dopaminergic nerve cell bodies in such areas as the substantia nigra tend to be pigmented due to the presence of the black pigment melanin.

Examples
There are eight dopaminergic pathways, but the four major ones are:

Minor ones include the incertohypothalamic pathway within the hypothalamus, which has a role in sexual behaviour.
