REM Sleep

A view of the inside of the right side of the brain showing five different experimental cuts. Figure 28. A view of the inside of the right side of the brain showing five different experimental cuts. Further studies showed that it is only the sides of the pons toward the cerebellum that are responsible for this task. A group of interacting cells, called REM-on cells, are located here among other types of cells. Each of these interacting REM-on cells is involved with one or more...

Characteristics Of Dreams

How Much are Dreams Like Waking Experiences How do dreams compare to our waking visual experiences In a clever experiment, Rechtschaffen and Buchignani (1983) prepared 129 variations of a single photograph. They varied the degree of fuzziness in the foreground and in the background, the brightness, the color intensity, and so forth. They then awaked 22 subjects from REMS and asked them to choose the photograph that best matched the visual quality of their dream. Four out of 10 times, they...

Circadian Rhythm Sleep Disorders

W.N. is a 20-year-old student living in the dorm at a nearby college. During the intake interview, he was reasonably alert and energetic, yet looked tired. He was 20 minutes late for his 11 a.m. appointment. He described his problem as insomnia. I just can't get to sleep. The problem started this semester, midway through the first semester of his junior year, when he had to take a required course only offered at 8 a.m. He said he was lucky when he started college to have no early-morning...

Problems That Occur During Sleep

Mark Twain called snoring sleeping out loud. Other wags have called snoring sound sleeping. Snoring, however, can indicate serious problems and may cause some of those problems. It occurs when there is less room for the air to travel through the upper airways during sleep. The air has to move faster through the space and causes vibrations of the soft tissue of the throat, like a flag flapping in a stiff breeze. Anything that constricts the upper airway passages or results in there being more...

Idiopathic Hypersomnia

Some people are sleepier than others for no known reason. A few feel tired almost all of the time, and others sleep a great deal longer than the average. Some of these very sleepy people are classified as having idiopathic, meaning not caused by something else, hypersomnia. It is not common, but it is striking when it occurs. It is not a result of insomnia, poor sleep, or other known sleep pathologies. It just happens. Beginning sometime between ages 15 and 25, they feel almost constantly...
