Chapter 10 Outline
Introduction: When Sleep Gets Out of Control
PART I Biological Rhythms
Many Animals Show Daily Rhythms in Activity
Circadian rhythms are generated by an endogenous clock
The Hypothalamus Houses a Circadian Clock
RESEARCHERS AT WORK: Transplants prove that the SCN produces a circadian rhythm
In mammals, light information from the eyes reaches the SCN directly
Circadian rhythms have been genetically dissected in flies and mice
PART II Sleep
Human Sleep Exhibits Different Stages
We do our most vivid dreaming during REM sleep
Different species provide clues about the evolution of sleep
Our Sleep Patterns Change across the Life Span
Mammals sleep more during infancy than in adulthood
Most people sleep appreciably less as they age
Manipulating Sleep Reveals an Underlying Structure
Sleep deprivation impairs cognitive functioning but does not cause insanity
SIGNS & SYMPTOMS: Total Sleep Deprivation Can Be Fatal
Sleep recovery may take time
What Are the Biological Functions of Sleep?
Sleep conserves energy
Sleep enforces niche adaptation
Sleep restores the body and brain
Sleep may aid memory consolidation
Some humans sleep remarkably little, yet function normally
At Least Four Interacting Neural Systems Underlie Sleep
RESEARCHERS AT WORK: The forebrain generates slow wave sleep
The reticular formation wakes up the forebrain
The pons triggers REM sleep
PART III Sleep Disorders
Sleep Disorders Can Be Serious, Even Life- Threatening
A hypothalamic sleep center was revealed by the study of narcolepsy
Some minor dysfunctions are associated with sleep
Some people appear to be acting out their nightmares
Insomniacs have trouble falling asleep or staying asleep
Although many drugs affect sleep, there is no perfect sleeping pill
Everyone should practice good sleep hygiene
