Preface
The link between what a physician sees in patients and the life processes is pathophysiology. Physiology and pathophysiology are the basis of clinical symptoms and signs; they in turn are the result of cellular and biochemical processes. All life processes are regulated. For a long time it has been known that the regulation of physiological (or pathophysiological) processes changes depending on time, for instance heart rate or respiration during the day and at night. This was understood in the past to be more or less two sides of one coin, and the causes of these processes thought to be solely one regulating principle. It has only recently been understood that sleep itself changes the program behind the regulation, which is moreover dependent on the stage of sleep. Regulation during sleep is not merely a mirror of those during wakfulness periods, but follows different rules. The analysis of the phenomena related to sleep has provided much new information in the past 10 years, profoundly changing our interpretation of the events occurring at night. This holds true particularly for the regulation of breathing. Work performed in the last few years has demonstrated that sleep can not only be viewed as a phase of relaxation or rejuvenescence and is the most healthy period in human life; on the contrary it has become clear that sleep may, in particu
