Dopamine is involved in the frontal cortex in executive functions like attention.t has far more roles in the brain to play. For example, dopamine plays a big role in starting movement, and the destruction of dopamine neurons in an area of the brain called the substantia nigra is what produces the symptoms of Parkinsonâs disease.
The nucleus accumbens (NA) is a small part of the brain that is important for motivation, pleasure, and addiction. Sometimes called the brain's âpleasure center,â this cluster of neurons modulates the effects of the neurotransmitter dopamine, on which many neural circuits depend.The nucleus accumbens is a link in the brain pathways that cause addiction and depression.Damage to this region of the brain causes a lack of motivation and inhibits addictive behavior.inked to other other parts of the brain that modulate cycles of reward for behavior, the nucleus accumbens is part of a set of neural pathways that facilitate learning new behaviors by pleasurable reinforcement.
