http://www.ceri.com/melaton.htmEffects of Melatonin Treatment In order to discuss Melatonin as a drug and its effects on behavior we need to define Melatonin and what role it plays in relation to brain and behavior. Melatonin is a hormone that is secreted into the bloodstream by the pineal gland. The pineal gland is a small, pea sized structure near the center of the brain. Signals from the eyes regulate the secretion of Melatonin. A person's internal clock, will fluctuate between a 23-25 hour a day cycle. Therefore, our Melatonin levels decrease and increase with the rising and setting of the sun, which aid to putting an individual on a 24 hour awake/sleep cycle.(1) The actual effects of taking Melatonin orally have been disputed for quite some time. Some facts that I had picked up were that Melatonin levels decrease with age. This decline can account for the difficulty many elderly people have with falling asleep. As the pineal gland breaks down, less and less Melatonin is being released, therefore making it more difficult to regulate the internal clock. There is still a lot of information about Melatonin that remains unknown. There is much controversy as to what the drug actually can, and does, do. Many people claim that it is capable of extending a person's life, "curing" insomnia, working as an anti-oxidant, changing a person's mood, de-stressing people, improving one's sexual life, and curing certain types of depression, but many believe otherwise. (2) I am not thoroughly convinced either way because of the contrasting opinions. I decided to make my own observations and come to my own conclusions by conducting a little experiment of my own. I am going to focus on just the effects of whether or not Melatonin will aid people in getting sleep. Observation has always been a simple way for me to derive whether or not something actually works. But in light of our class discussion, I do not know if that is the most appropriate way to look at things. We have discussed that some behavior is internal and we do not see that on the exterior of the body. But for all intents and purposes, my observations for the effectiveness of Melatonin were external ones. My internal clock is really messed up. I usually sleep until 9:30 in the morning, but never head off to bed before 3 or 3:30. So Melatonin looked like a very appealing idea to procure a little more sleep.
