      Its main function as a hormone is to inhibit the release of prolactin from the anterior lobe of the pituitary. A family of at least 5 Dopamine Receptors (DR) genes, D1-D5, have been identified based upon the amino acid identity, pharmacological specificity and effector responses.

      Modulation of cortical function can be achieved via the D1, D2, D3 and D4 dopamine receptors, leading to the "fine tuning" of information processing. D1 and D2 are high in the striatum, D3 is located in the nucleus accumbens and D4 is high in the frontal cortex and limbic areas.

      Dopa decarboxylase catalyses the decarboxylation of levodopa to produce dopamine. Dopamine β -hydroxylase catalyses the oxidation of dopamine in order to introduce an alcohol function leading to the formation of noradrenaline. N-Methyl transferase introduces a methyl group onto the nitrogen atom of noradrenaline. Page reference: 595-596. a.

      Receptors of dopamine are linked to the divergent thought process. Creative people, as well as schizophrenic people, have more density of these receptors in the thalamus. This means that it intervenes in cognition and reasoning and more information will flow through the brain.

      dopamine and serotonin receptors. These drugs seem effective in reducing both positive and negative symptoms and therefore it is possible that negative symptoms are linked to an excess of serotonin. Also, it should be noted that serotonin regulates dopamine levels in areas such as meso-limbic pathway and this demonstrates how important it is to ...

      Other theories suggest that the crucial role of dopamine may be in predicting pleasurable activity. Related theories argue that dopamine function may be involved in the salience ('noticeableness') of perceived objects and events, with potentially important stimuli (including rewarding things, but also things which may be dangerous or a threat) appearing more noticeable or more important.
