Chapter 14: Biological Rhythms, Sleep, and Dreaming
OVERVIEW OF THIS CHAPTER
Much of our experience of the es in cycles: the endless parade of the seasons, the waxing and waning of the moon, dawn breaking and night falling. Organisms blend themselves into all these rhythms seamlessly, and viewed objectively, rhythmicity is a remarkably pervasive feature of daily life. Modern research is revealing that diverse processes, ranging from gene transcription to human conception rates, are subject plicated overlapping cyclical patterns. The first part of the chapter provides an introduction to the functioning and neural bases of the biological timepieces that track and predict rhythmic environmental events. The remainder of the chapter is devoted to sleep, a phenomenon whose mechanisms remain among the most mysterious of rhythmic behaviors. Disorders of sleep are the subject of much current research, and they receive considerable coverage in the latter part of the chapter.
