Sleeping Disorders and the I-Function :: Biology Essays Research Papers

Sleeping Disorders and the I-FunctionAs we all know, residual is an important part of our lives. Without the proper amounts and type of sleep, run down and other problems can arise. Generally, we can clear distinguish in the midst of 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 consort to the I-function and consciousness? Each sleeping disorder has its own unique solvent to this question. It is essential to understand sleep to fully appreciate it. However, many aspects of it endure a mystery. We do have some degree of understanding of sleep. at bottom our sleep cycle a type of unusual sleep occurs, rapid eye movement sleep. During this cycle the designs of REM sleep are interspersed with slow wave sleep in alternation. Each period of REM sleep ( at that place are ordinarily 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 use 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 signal 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 inactivate (normally the body inhibits any movement). The autonomic nervous system also alters its behavior. The prescript of body temperature is lost and the blood pressure, heart rate, respiratory rates projects change magnitude variability. REM sleep can be detected by measure 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. It is fascinating that at this point, REM sleep, where dreamin g is frequent, the body shuts itself down. If, as suggested in class, the I-function is active at this stage, it is interesting that all body movement is inhibited. During other stages in which there are synchronized EEGs, and the I-function is not supposed to be present, the body does not inhibit all motor activity. This seems to imply that when the I-function is present it will go through the body as it sees fit. One of the more ubiquitous parasomnias is sleep talking or somniloquy.
