Running on low sleep can also negatively affect your health. *All content and webpages on this website were created by High School students. “A little bit of dopamine is good,” says Paul Shaw, a sleep researcher at Washington University in St. Louis. This site gave me more insight as to why people need sleep and when they need it. We all know the importance of a good night’s sleep. Some people’s brains are better at this than others letting them perform well on tests and pick up new information even after staying up all night. According to new research, dopamine is what keeps people who don’t get enough sleep from conking out.

That is why people tend to wake up when the sun rises and why some people need absolute darkness to sleep. Melatonin inhibits alertness and induces sleep. Electroencephalographic studies have In cyclic fashion these two systems apply brakes to the reticular activating system responsible for wakefulness and also influence all the other nerve systems in the brain, notably those involved in dreaming.

I love sleep with a passion, even though I do not personally get enough of it.

Both are naturally occurring in the brain. I chose this project because sleep … Dopamine is a complicated chemical, and sleep-deprivation is a complicated state of mind. Running on low sleep can also negatively affect your health. The Chemistry of Sleep Paralysis. After a few early mornings, extreme fatigue might make you feel like you’re going to fall over. The other main chemical found during sleep is melatonin, which has a chemical equation of C13H16N2O2. Weekly updates to help you use Science News for Students in the learning environment. This project explains the chemistry behind sleep and what goes on during the sleep cycle, chemically speaking. Founded in 2003, Science News for Students is a free, award-winning online publication dedicated to providing age-appropriate science news to learners, parents and educators. The Chemistry of Sleep. On this site I found information about melatonin, which is another major chemical found in sleep. Peter Wall is currently a junior at Billings Senior High. Let us suppose that the deprivation of paradoxical sleep causes a certain substance related to the nervous system to accumulate. The scientists tested each person’s memory and ability to pay attention twice: once after a good night’s sleep and once after being kept up all night long. However, melatonin is extremely sensitive to light. Other people have a really hard time paying attention when exhausted, and their reaction times slow way down. A brain chemical called dopamine can help you stay alert even when you feel tired.

A single injection of the drug nialamide, for example, will eliminate paradoxical sleep from the cycle for a period of hundreds of hours.

However, this chemical is interrupted by light.

Sleep is a dynamic process which involves continuing brain activity which acts to produce and release hormones and proteins essential for organ system regulation as well as growth as tissue repair. Higher levels of dopamine, the study suggested, kept the volunteers awake even though they felt tired. It is the body’s natural reaction when it need to “recharge its batteries”.
Share. “More is bad. We have also found that this potent drug can suppress paradoxical sleep in cats that have first been deprived of such sleep for a long period in the pool experiment. I learned about adenosine and melatonin on this and some of their roles in sleep. There are two main chemicals that are found in the brain during sleep. Melatonin is created by the pineal gland in the brain. Further, the injection of certain precursors involved in the synthesis of serotonin in the brain can produce a state resembling light sleep, whereas drugs that selectively depress the serotonin level in the brain produce a state of permanent wakefulness. Tweet. With the discovery of its objective accompaniments and the intriguing phenomenon of paradoxical sleep, however, it seems that we have set foot on a new continent that holds promise of exciting explorations. Melatonin is stimulated by the approach of night, but it starts to go away once light is introduced. However, melatonin is extremely sensitive to light. The researchers found that higher levels of dopamine don’t fend off the trouble people have thinking and learning while sleep-deprived. During the tests, the scientists measured levels of dopamine in the brains of the volunteers. Eventually, your body will take over and will force you to sleep. As you go throughout your day, your body burns energy and as it does that adenosine is created. The Chemistry of Sleep. “A little bit of dopamine is good,” says Paul Shaw, a sleep researcher at Washington University in St. Louis.

This project explains the chemistry behind sleep and what goes on during the sleep cycle, chemically speaking. In the last 15 years there has grown up the concept of the brain stem reticular activating system. Some people are miraculously able to think clearly and react quickly, even when they haven’t had much sleep. On this site, I found information on the different cycles of sleep and how they work and how much sleep an average human needs. A chemical in the brain called dopamine might be part of the answer. I learned about the REM cycle, how sleep helps us, sleep and circadian rhythms,and sleep disorders. For the future, Peter plans to go to college and pursue a career in sports management and have a family.
The problem of defining sleep in biochemical terms is extraordinarily difficult, yet studies in this area are numerous and have a long history.
