Ventral Tegmental Area (VTA) is the area that synthesizes dopamine, which then sends to nucleus accumbens. Nucelus accumbens is the pleasure center, and it is stimulated by the neurotransmitter dopamine from VTA. VTA also sends dopamine to prefrontal cortex which regulates and controls these impulses. The locus coeruleus is the area packed with norepinephrine; and when stimulated by a lack of the addictive substance, will drives the person to do anything necessary to obtain a fix.

Locations of the substantia nigra and the ventral tegmental area in the midbrain

Researchers at the University of North Carolina (UNC) School of Medicine have discovered an area in the brain responsible for triggering attraction and causing us to notice the opposite sex.

Know your brain: Ventral tegmental area

The ventral tegmental area (VTA), a group of neurons at the very centre of the brain, plays an especially important role in this circuit. The VTA receives information from several other regions that tell it how well various fundamental needs, and more specifically human needs, are being satisfied.

Early life stress confers lifelong stress susceptibility in mice via ventral tegmental area

The major dopamine pathways in the brain are involved in motor control, motivation, and reward. Dopamine neurons in the ventral tegmental area (VTA) project to the frontal cortex, nucleus accumbens, and other areas, and these neurons play an important role in motivation and reward. Motor control is governed by dopamine pathways from the substantia nigra to the striatum.

The image shows the dopamine pathway with the nucleus accumbens and frontal cortex highlighted.

Major dopamine pathways. 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. The motor functions of dopamine are linked to a separate pathway, with cell bodies in the substantia nigra that manufacture and release dopamine into the dorsal striatum.
