Consciousness
our awareness of internal and external stimuli
Sleep
a state characterized by relatively low levels of physical activity and reduced sensory awareness
Wakefulness
as state characterized by high levels of sensory awareness, thought, and behavior
Biological rhythms
internal rhythms of biological activity (ie menstruation)
Circadian rhythm
a biological rhythm that takes place over a period of about 24 hours (ie the sleep-wake cycle)
Suprachiasmatic nucleus (SCN)
the area of the hypothalamus the brains clock mechanism is located in
Jet lag
a collection of symptoms that results from the mismatch between our internal circadian cycles and our environment

Sleep debt
when an individual does not get sufficient sleep on a chronic basis
Sleep rebound
when a sleep-deprived individual tends to take a shorter time to fall asleep during subsequent opportunities for sleep
Sleep involves the secretion and regulation of a number of hormones from several endocrine glands including
melatonin, follicle stimulating hormone (FSH), luteinizing hormone (LH), and growth hormone
Melatonin
involved in the regulation of various biological rhythms and the immune system
FSH and LH
important in regulating the reproductive system
Growth hormones
important for in physical growth, maturation, and other metabolic processes
Sleep is divided into two phases
REM sleep and non-REM (NREM) sleep
Rapid eye movement (REM) sleep
darting movements of the eyes under closed eyelids
non-REM (NREM)sleep
subdivided into four stages distinguished from each other and from wakefulness by patterns of brain waves
Stage 1 sleep
a transitional phase that occurs between wakefulness and sleep, the period during which we drift off to sleep
Stage 2 sleep
the body goes into a state of deep relaxation
Sleep spindle
a rapid burst of higher frequency brain waves that may be important for learning and memory
K-complex
a very high amplitude pattern of brain activity that may occur in response to environmental stimuli
Stage 3 and 4 sleep
deep sleep or slow-wave sleep
REM rebound
when people are deprived of REM sleep and then allowed to sleep without disturbance, they spend more time in REM sleep to make up for lost time
Manifest content
the actual content, or storyline, of a dream
Latent content
the hidden meaning of a dream
Collective unconscious
a theoretical repository of information Jung believed to be shared by everyone
Lucid dreams
dreams in which certain aspects of wakefulness are maintained during a dream state
Insomnia
a consistent difficulty in falling or staying asleep
Cognitive-behavioral therapy
a type of psychotherapy that focuses on cognitive processes and problem behaviors
Parasomnia
one of a group of sleep disorders in which unwanted, disruptive motor activity and/or experiences during sleep play a role

a sense of panic thats often followed by screams and attempts to escape from the immediate environment
Sleep Apnea
episodes during which a sleepers breathing stops
There are two types of sleep apnea
obstructive sleep apnea and central sleep apnea
Obstructive sleep apnea
occurs when an individuals airway becomes blocked during sleep, and air is prevented from entering the lungs
Central sleep apnea
disruption in signals sent from the brain that regulate breathing cause periods of interrupted breathing
Sudden Infant Death Syndrome (SIDS)
an infant stops breathing during sleep and dies
Narcolepsy
when an individual cant resist falling asleep at inopportune times
Physical dependence
changes in normal bodily functions-the user will experience withdrawal from the drug upon cessation of use
Psychological dependence
an individual has an emotional need for the drug and may use the drug to relieve psychological distress
Tolerance
linked to physiological dependence, and occurs when a person requires more and more drug to achieve effects previously experienced at lower doses
Alcohol
in a class of psychoactive drugs known as depressants
Low doses
feelings of euphoria
High doses
feeling sedated
Depressant
a drug that tends to suppress central nervous system activity
Stimulants
drugs that tend to increase overall levels of neural activity
Examples
cocaine, amphetamines, cathinones, MDMA, nicotine, and caffeine
Opioid
one category of drugs that includes heroin, morphine, methadone, and codeine
