How many battalion really do romance? E actuallyone dreams, whether the dream is remembered or not. Throughout the night, there are many stages of peacefulness that everyone goes through. These stages embarrass light sleep, deep sleep, and dream sleep. Nightmares are also considered dreams, just caused by different emotions. Scientists also have many electrical appliances and have through many tests to study dreams.Dreams are very complex things. Scientists have a hard time trying to understand why the great unwashed dream. Although recently, neurosurgerys precise methods of research and invention of sophisticated electrical appliances, have enabled the scientists to amplify their knowledge of the human brain, nervous systems, and the bodys biochemistry (Strachey 20). The invention of the electroencephalograph, otherwise known as an EEG, has made it possible for a trained performer to read the brains reactions during wakefulness, rest, and sleep (Schneider). The machine detec ts and enormously amplifies the very faint electrical impulses produced by the brain placing electrodes against subjects scalp (Freud). Professor Nathanial Kleitman of dinero university, discovered that babies have a sleep rhythm of fifty to threescore minutes after which they are inclined to wake up, although obviously they coffin nailt always(Freud). As children grow, the body begins to develop the ninety-minute cycle associated with expectant sleepers. The pattern of sleep is acquired and controlled by environmental and social conditioning. However, as people grow older the body tends to revert to the naptime habits of babyhood (Freud). Yet, though people more or less choose when to sleep, the basic ninety-minute rhythm remains. It is biologic and not controlled by consciousness, rather as a healthy somebodys metabolism functions autonomously (Parker 93). Eugene Aserinsky noticed that after an infant fell hypnoid its affectionatenesss moved beneath the closed lids. Also, a t intervals during sleep and was the first movement when the baby began to wake(Freud). Kleitman and Aserinsky decided to investigate whether such a pattern could be found in adult sleepers as well (Freud). By attaching extra electrodes from the EEG machine to areas around declare oneself sleepers eyes, the two scientists were able to monitor brain impulses and movements, speckle measuring respiration and body movements (Freud). The scientists concluded that there were two types of eye movement. Slow as found in babies and very fast movements, this could wear from a few minutes to over a half an arcminute (Freud). These rapid eye movements, which are commonly known as REMs appeared to go across at intervals throughout the night (Beare).
