In the brain, dopamine plays an important role in the regulation of reward
and movement. As part of the reward pathway, dopamine is manufactured in nerve
cell bodies located within the ventral tegmental area (VTA) and is released in
the nucleus accumbens and the prefrontal cortex. Its motor functions are linked
to a separate pathway, with cell bodies in the substantia nigra that manufacture
and release dopamine into the striatum.
