Sleep is a natural persisting state of mind and body which is also a basic need of human. The hormone that control sleep and wake cycle is called a Melatonin. Melatonin is secreted by the smallest gland in the brain called the pineal gland.
Sleep is divided into two types non-rapid eye moment and Rapid eye moment. Non-REM sleep is a first stage, which is dreamless sleep. In this stage, the vital signs are slow and regular; respiration, heart rate and blood pressure. Rapid Eye Moment sleep occurs in cycles of about 90-120 minutes throughout the night. The vital signs are more rapid and irregular during this stage. Sufficient sleep helps to boost the brain power which contributes to several important cognitive, emotional and performance related

  • Effects 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)

  • Sleeping Disorders and the I-Function

    1463 Words  | 3 Pages

    As we all know, sleep is an important part of our lives. Without the proper amounts and type of sleep, fatigue and other problems can arise. Generally, we can clearly distinguish between a sleeping person and a person that is awake. With sleeping disorders, the distinction between an awake person and a sleeping person becomes more intriguing. What is the difference, how does it relate to the I-function and consciousness? Each sleeping disorder has its own unique answer to this question. It is essential to understand sleep to fully appreciate it. However, many aspects of it remain a mystery. We do have some degree of understanding of sleep. Within our sleep cycle a type of unusual sleep occurs, REM sleep. During this cycle the periods of REM sleep are interspersed with slow wave sleep in alternation. Each period of REM sleep (there are usually 4 or 5 periods a night) lasts for approximately 5 to 30 minutes. During these periods a sleep paradox occurs. An enormous amount of brain activity takes place; this is sometimes even more activity then when awake. This clearly indicates that sleep is not simply to rest our mind and not to think. So, during this period our brains are extremely active, yet there is usually no input or output. During this period, along with the random eye movement (REM), there is a complete loss of muscle tone. Essentially, at this point, the motor system is paralyzed (normally the body inhibits any movement). The autonomic nervous system also alters its behavior. The regulation of body temperature is lost and the blood pressure, heart rate, respiratory rates shows increased variability. REM sleep can be detected by measuring the electrical activity of the brain with an electroencephalogram. At this point, the EEG will show the same pattern of activity as when the brain is awake.

  • Sleep Physiology And Chronobiology Essay

    1611 Words  | 4 Pages

    We live our entire life in two states, sleep and awake1. These two states are characterized by two distinct behaviors. For instance, the brain demonstrates a well-defined activity during non-REM sleep (nREM) that is different when we are awake. In the study of sleep by Huber et. al., the authors stated that sleep is in fact a global state2. It is unclear whether this statement means that sleep is a state of global behavioural inactivity or the state of the global nervous system. The notion that sleep is a global state of the nervous system served as basis for sleep researchers to search for a sleep switch. The discovery of the sleep switch, in return, provided evidence and enhanced the notion that sleep is a global state of the nervous system. The switch hypothesis developed from the fact that sleep can be initiated without fatigue and it is reversible1. It was hypothesized that there is something in the brain that has the ability to control the whole brain and initiate sleep. Studies have found a good candidate that demonstrated this ability3. They found a group of neurons in the Ventrolateral Preoptic (VLPO) nucleus. It was a good candidate because it was active during sleep, has neuronal output that can influence the wakefulness pathway, and lesion in the area followed reduce sleep3. The idea that there is something that can control the whole brain and result sleep state supports the idea that sleep is a global state of the nervous system.

    Sleep is one of our basic needs to survive and to function in day to day operations, but not everyone needs the same amount of sleep. Some people can survive on very little sleep, i.e. five hours a night, and some people need a lot of sleep, to the extend that they are sleeping up to 10 to sometimes 15 hours a night (Nature, 2005). According to Wilson (2005) the general rule states that most people need from seven to eight hours of sleep. The deprivation of sleep in our society in continually increasing with the demands in society increasing work loads, the myth that a few hours of sleep is only necessary to function properly and that sleep is sometimes considered as killing time (Nature, 2005). Sometimes sleep deprivation is also caused by other situations like sleep disorders, i.e. sleep apnea, chronic insomnia or medical conditions such as stress (Wilson, 2005).

    the sleeper will gradually descend deeper into sleep, becoming more and more detached from the outside world and progressively more difficult to awaken. Stage three is the beginning of deep sleep, occurring about thirty to forty five minutes after you first fall asleep. The deepest sleep occurs in Stage four. Stage three and four has the biggest and slowest brain wave. REM sleep, a mentally active period during which dreaming occurs, provided a biological explanation for this phenomenon. Scientists found that brain activity during REM sleep begins in the pons, a structure in the brainstem, and neighboring midbrain regions. The pons sends signals to the thalamus and to the cerebral cortex, which is responsible for most thought processes. There are several myths about sleep. For one, how much sleep a person should get? According to our text book people should sleep for at least eight hours to maintain sound mental and physical health. But every one doesn’t get the chance to sleep for that amount of time. There is no normal amount of time you should sleep. Everyone is not the same. For one I might sleep for five hours and feel refreshed enough to work another shift. Other hand my cousin might need more then eight hours of sleep to feel refreshed.

  • Sleeping Disorders: The Five Stages Of Sleep

    465 Words  | 1 Pages

    At night as we fall asleep, our body goes through several different stages. These stages consist of light and deep sleep. There are around 5 stages in a cycle and we go through four to five cycles every single night. Stage 1, Stage 2, Stage 3, Stage 4, and last REM (rapid eye movement) You do not go straight from deep sleep to REM (rapid eye movement). The first couple cycles have a shorter time in REM and longer deep sleep. Later on in the night, you have a longer time in the REM stage and shorter time in deep sleep. However, you never go straight from deep sleep to the REM stage. You actually go from light sleep to deep, back to light, and finally to REM. A full cycle lasts anywhere between 100-120 minutes but the first cycle on lasts about 90 minutes. Each stage takes anywhere between 5-15 minutes.

    What research has told us is that sleep is relegated by an internal time clock or what the experts call the circadian cycle. First circadian comes from two Latin words circa: about and dia: day. All the various bodily function cycle that occur during the day are related to our circadian cycle. Since the time of Aristotle and Hippocrates these cycles have been recognized. Our sleep/wake cycles is one of the best known bodily functions to show circadian rhythms, and even our vital signs are directly linked to this cycle. As technology advances we gain more precise measurements, allowing researchers to recognize more circadian cycles which in turn teach us how our bodies work and function. On an interesting note it has been found that bone length is linked to and show a circadian cycle.
