An inhibitor dampening activity so we stay rooted. Travels along pathways into the brain. Plays different roles: Dopamine in the basil ganglia (in brains interior) show they are critical for executing smooth and controlled movements. Lack of dopamine is a cause of parkinson disease which a person looses the ability to initiate controlled movements. Dopamine moves into frontal lobe regulating flow of information coming in from other areas of the brain. Compromise in the flow of dopamine may cause disrupted or incoherent thought as in schizophrenia. In milder disorders, too much dopamine in the limbic system and not enough in the cortex may produce an overly suspicious personality giving to bouts of paranoia or may inhibit social interaction. A shortage of Dopamine in the frontal lobes may contribute to poor working memory. Dopamine is also thought to produce feelings of bliss (the pleasure chemical). More dopamine into the frontal lobe lessens pain and increases pleasure. |
