Awareness
sensory
self -emotions -feelings
Freud stuff
Altered States
-when asleep -> less aware of self -sleeping, dreaming, drug use, hypnosis
Why sleep?
it allows us to conserve energy, repair damage to the body, and store and organize information.
rid waste - in the brain -> if not asleep, not able to "rid waste" -physical -mental
immune system - sick; injured
How? (much)
Babies = 10-14 hours (maybe 20)
Adults = 7-9 hours
Sleep Debt - hard to get rid of
Circadian Rythms
24 bio clock
jet lag
melatonin (hormone) - sun -> hypothalamus -> pineal gland
manage what time we go to bed
Sleep Stages
brain waves
Stage 1 - alpha waves: neural activity decreases
Stage 2 - sleep spindles: neural activity decreasing. Easily woken up.
Stage 3 & 4 - "deep sleep" - delta waves : brain is least active. Feel worse after getting 8 hrs. of sleep.
REM
REM
"Paradoxical Sleep": Brain extremely active -> body is "locked down"; body doesn't move.
Dreaming
Rapid eye movement
Cycles
20 minute nap = coffee; 6-8 hrs. of energy; Stage 1 & 2 90 minutes = more energy (boost); Awake -> REM Stage 3 & 4 - danger zone
3/4 -> REM; REM increases the longer you sleep
REM Rebound - put body in REM earlier & stay in longer
Most in stage 2
Dreaming
Pons
Evolution -threat perception
Biological -long-term potentiation/info processing (memory consolidation) -Activation Synthesis
Psychoanalytic (Freud) -unconscious: work through conflicts in a safe way through dreaming -manifest vs. latent content
Psychodynamic (Carl Jung) -collective unconscious
memory consolidation
rerunning routs in brain
threat perception
fear, loneliness, embarrassment, etc.
activation synthesis
random things in dream
manifest content
story of the dream - part you remember
latent content
hidden meaning of a fantasy or dream
collective unconscious
cloud; google doc; Things are connected in a universal way. Things are the same to everybody
where does dreaming occur in the brain?
