Back in the mesolimbic pathway, dopamine can play a role in psychosis, and many antipsychotics for treatment of schizophrenia target dopamine. 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 mesolimbic pathway, which originates in the middle of the brain and branches to various places like the cerebral cortex, is the most important reward pathway in the brain. One of the mesolimbicâs stops is the nucleus accumbens. Increased dopamine in the nucleus accumbens signals feedback for predicting rewards. Your brain recognizes that something important â good or bad â is about to happen, thus triggering motivation to do something.
