CONSCIOUSNESS
STATE OF BEING AWARE
-reflecting on environment or internal experience that simply reacting to them
circadian rhythm
predictable pattern of hormone levels, body temperature and wakefulness
brain waves
electrical currents in the brain
what are the five cycles of sleep
1) awake
2) stage 1
3) stage 2
4) stage 3
5) stage 4
what happens in sleep cycle during awake but relaxed state?
brain produces ALPHA waves , relatively slow and regular
what happens in stage 1 sleep
slower breathing and irregular erratic brain waves
- falling or floating experience
- alpha waves replaced with slower THETA waves
hypnogogic
having to do with drowsiness, falling or floating experience
-happens in first five minutes of sleep
stage 2 sleep
DEEPER RELAXATION occasional bursts of rhythmic brainwaves
sleep spindles
occasional burst of rhythmic brainwaves that occur in stage 2
stage 3
brains starts to produce DELTA waves
stage 4
much stronger more consistent delta waves
slow wave sleep
most difficult time to wake up
-sleep between stage 3 and 4
REM
- rapid eye movement
- irregular erratic brain waves,breathing more rapid, irregular, heartbeat increases
- WHEN people DREAM
PARADOXICAL SLEEP
- REM SLEEP
- body appears calm and relax despite cortical activity
insomnia
difficulty falling asleep or staying aslep
narcolepsy
sudden, uncontrollable attacks of sleep during waking hours
-sometimes narcoleptic go directly to REM completely losing muscular tension
sleep apnea
stops breathing intermittently during sleep
dreams according to freud
- a way to preserve sleep
- the images in dreams disguised as repressed desires to avoid anxiety
manifest content
actual images that appear in a dream
latent content
forbidden sexual or aggressive desire that dreamers would repress if awake
activation synthesis theory
brain’s neurons fire randomly during sleep, as we wake we construct a dream to try to make sense of out of the random images
information-processing
dreams are ways to consolidate information into memory
what happens when deprived of dreams?
we make up for it by later experiencing prolonged periods of REM sleep
REM rebound
prolonged period of REM sleep
