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
Circadian Rhythm
24 hr cycle of the body

jet lag
Sleep Stages

N1 Transitioning (5-10min)
beta = 20 cyc/sec
alert person
alpha = 10 cycles/sec
relaxed person
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
30 min
bed wetting & sleep walking
Paradoxical Sleep
eyes, breathing, brain
voluntary muscles - paralysis
90 min
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

Information Processing
- you dream about what you did that day.
Problem-solving mechanisms.
Emotional regulation.

Physiological Theory
- may promote neural development and preserve neural pathways.
Brain Plasticity
- Restructuring and reorganizing of the brain related to learning and memory.
Brainstem Activation
- half brained sleeping vs. whole brain and brainstem activity. Perhaps REM keeps our brainstems active.

Neural Activity
- nothing other than a byproduct of REM sleep.
Altered States of Cssnss

Substance Abuse
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

Voluntary process

individual-driven form of consciousness

deep thought

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

Sleep Disorders
Sleep Apnea
Drug Use
Déjà vu
Narcotics: relieve pain and induce euphoria
