Can someone explain the properties of dopamine and how it is an excitatory and inhibitory neurotransmitter all at once? What role does it play in Parkinson's Disease and how is it produced (chemically)?

Answer & Explanation:

Whether dopamine is excitatory or inhibitory depends on the type of effect on the target neuron, on the type of receptor on the surface of the neuron membrane, and on how the neuron responds to an increase or decrease in concentration of cAMP levels in specific. Studies have shown that symptoms of Parkinson's disease develop in patients with an 80% or more loss of dopamine-producing cells in the basal region. Normally, dopamine works in a delicate balance with other neurotransmitters to help coordinate the millions of nerve and muscle cells involved in movement. People with Parkinson's disease have involuntary or uncontrolled movements, such as tremors, stiffness, and difficulty with balance and coordination that are thought to be caused by a lack of dopamine balance.

Olivia is a veterinary parasitologist who is studying a recent outbreak of giardia among beavers in a Colorado river. Since this is the first time she has seen beavers with this type of protozoa, Olivia is attempting to trace where they contracted it. After extensive testing, it is found that human sewage was leaking from a treatment plant nearby. This sewage contained the giardia protozoa, and the beavers picked it up in the nearby waters. Olivia now writes a research paper concerning this case in order to reclassify giardia. After her investigations, into what category is Olivia MOST likely hoping to place these protozoa in?
