States of Consciousness
Transcript of States of Consciousness
Why do we sleep? Why do we dream? Is it crucial that we do so?
Awareness without awareness
William James' effort of attention
shifting attention aka multitasking
focus on the tasks with the least experience
Awareness of one's own thoughts, feelings, memories, sensations, and environment.
Medically - cssnss vs. uncssnss = opposite states
Psychologically - we exist in various states of cssnss
The brain registers just about everything and processes each stimulus individually - why don't we remember everything?
Freud - We are onions
uncssnss = memories & urges that are painful, unpleasant, unacceptable, or cause feelings of anxiety or conflict
24 hr cycle of the body
N1 Transitioning (5-10min)
beta = 20 cyc/sec
alpha = 10 cycles/sec
theta = 3.5-7 cyc/sec
Interesting sensations e.g. myoclonic jerk
N2 Drowsy: heart rate & breath decrease
sleep spindles - bursts of rapid, rhythmic brain waves
N3 Transition light to deep
delta waves begin = less than 3.5 cyc/sec
N4 Delta Sleep
bed wetting & sleep walking
eyes, breathing, brain
voluntary muscles - paralysis
1, 2, 3, 4, REM
REM, 2, 3, 4
REEM, 2, 3, 4
REEEM, 2, 3, 4
What is a Paradox?
A paradox is a statement that apparently contradicts itself and yet might be true
For example: All Cretans are liars
Royal Road to the Unconscious
- symbolic manifest content of deeper latent content.
- reflections of personality/myth
- you dream about what you did that day.
- may promote neural development and preserve neural pathways.
- Restructuring and reorganizing of the brain related to learning and memory.
- half brained sleeping vs. whole brain and brainstem activity. Perhaps REM keeps our brainstems active.
- nothing other than a byproduct of REM sleep.
Altered States of Cssnss
intentionally altering cssnss
physical and/or psychological dependence
damage to nervous system, liver, death
tolerance and increase OR sensitization

Lost in thought
Trancelike State - neither alert nor asleep - in between
Heightened concentration and focus
More susceptible to suggestion
individual-driven form of consciousness
between excitement & dullness
stability & clarity are perfectly balanced
requires relaxation requires awareness
Brain & Immune
Education (attention & social skills)
Chronic pain issues or stress-related disorders
Start around 14:45 until 24:50
