Sleep Stages
Transitional phase occurring between wakefulness and sleep
- Rates of respiration and heartbeat slow down
- Overall muscle tension and core body temperature decrease
- Alpha waves
Stage 1
What sleep disorder involves an irresistible urge to fall asleep during waking hours?
Hint: Cataplexy
NARCOLEPSY
REM Sleep
Rapid Eye Movement
You are dreaming
Who is considered to be the father of psychology and created the first psychology laboratory?
Wilhelm Wundt
Known as slow-wave sleep
- Delta waves
- Respiration and heart rate slow down further
STAGE 3
What occurs when individuals stop breathing during their sleep, usually for 10-20 seconds
or longer.
SLEEP APNEA
Jet Lag
Symptoms resulting from the mismatch
between our internal circadian cycles and our
environment
Fatigue, sluggishness, irritability, and insomnia
For a correlation to be negative what must happen?
One variable must go one way while the other goes the opposite.
The body goes into deep relaxation
- Theta waves
- Characterized by the appearance of
both sleep spindles and K-
complexes
Stage 2
What sleep disorder is present when the muscle paralysis associated with REM sleep does not occur?
REM Sleep Behavior Disorder
Sleep Spindles & K-Complexes
Sleep Spindles – rapid burst of high
frequency brainwaves
K-Complexes – very high amplitude
pattern of brain activity
Active during stage 2
What is Psychology?
The scientific study of the mind and behavior.
REM
STAGE 4
What sleep disorder involves the airway becoming blocked and air is prevented from entering the
lungs?
Obstructive Sleep Apnea
Cataplexy
loss of muscle tone while awake or in some cases complete paralysis
of the voluntary muscles
What allows the two hemispheres of the brain to communicate?
Corpus Callosum
Rapid eye movements
- Paralysis of voluntary muscles
- Dreams
- Brain waves are similar to those seen during wakefulness
REM Sleep
what sleep disorder involves difficulty falling or staying asleep for at least 3 nights a week over at
least one month’s time?
Hint: Most common
INSOMNIA
Consciousness
awareness of internal and external stimuli such as feelings of hunger and pain or detection of light
