  1. Dopamine Landon Fry

  2. Where is it produced? • Dopamine can be produced in many regions of the brain that include the substantianigra and the ventral tegmental area.

  3. When does Dopamine become active? • Dopamine is active throughout your entire life, but can be more prevalent at any point within the life cycle. • Most commonly, dopamine is more active when a young child, which makes the youth sleep more.

  4. How does Dopamine enter the pituitary gland? • It is released by the hypothalamus and its action as a hormone is to release inhibitor or prolactin rom the anterior lobe of the pituitary gland. • The pituitary gland is the target cell for the hormone dopamine.

  5. How much is in the blood? • Found in blood plasma, 95% of the dopamine in the plasma is in the form of dopamine sulphate.

  6. What does dopamine cause the body to do? • In the kidneys: increase blood supply, increase filtration, increase excretion of sodium. • In the pancreas: synthesizes enzymes and other substances, and secretes them into the small intestine. • In the immune system: acts upon receptors present on immune cells, can affect immune cells in spleen, bone marrow, and circulatory system.

  7. What happens with atypical amounts of dopamine? • With more dopamine inside the bloodstream, the body begins to feel more tired. • There is no real underproduction of dopamine.

  8. Can dopamine be synthetically replaced? • Dopamine dysregulation syndrome (hedonistic homeostatic dysregulation in Parkinson’s disease) is a dysfunction of the reward system for patients with Parkinson’s disease. It can be characterized by problems such as addiction or gambling.

  9. How are people with atypical amounts treated medically? • There is no way to take away the dopamine from the blood stream without taking the blood out itself.
