DOPAMINE (do'pa-men): One of the most familiar catecholamines, dopamine, regulates how neurons react to stimuli and seems to play a central role in schizophrenia. A growing body of evidence suggests that dopamine is one of the most important of the chemicals that regulate cell activity associated with working memory. An imbalance in the abundance of dopamine in the prefrontal cortex can induce deficits in the working memory similar to those resulting from lesions in the principal sulcus region of the prefrontal cortex. DOPAMINE (synomym): music, when you are in need neural-audio stimulation.
