Q

What is the objective defintion of ASCs ?

A
  • Defines other consciousess via how they were induced (given rise to)
  • Eg: which drug and how long did it took till drug rises
  • Eg: defined via physiological patterns (heart rate)

Q

How do we in general determin different states of consciousness ?

A
  • Seeing the changes in mental fucntions which are currently linked to consciousness (perception memory)
  • Some ASCs change a lot of mental function compared to normal and other just some

Q

Explain laureys consicouness mapping:

A
  • Also only 2 dimensions:
  • > Arousal (lvl of consciousness) and awareness of enviorment (content of consciousness)
  • They both share a positive correlation
  • From Coma to wakefulness
  • Only exception is Rem sleep and wegetative state

Q

What is meant by activation energy according to the AIM model ?

A
  • It is the ratio between amines neurotransmitter and cholines neurotransmitter
  • Amines = means rational thoughts and direction of attention (high in awake)
  • Cholines: delusional and irrational thinking (high in REM)

Q

Explain the 4D model of consicouness mapping:

A
  • Activation: low to high arousal
  • Awareness: narrow to broad range of contents, available to conscious
  • Self-awareness: diminished (less) to heightened (more) self awareness
  • Sensory dynamics: reduced (less) to heightened (more) sensations
  • All four together create a C space

Q

What is meant by C space ?

A
  • space of states of consciousness
28
Q

What is meant by B space, according to the 4D model ?

A
  • space of functional brain states
29
Q

What is the combination between the B space and C space according to the 4D model of consciouness ?

A
  • B and C space create the phenospace

- phenospace = The possibility to move around consicounes states

30
Q

What is meant by meditation ?

A
  • procedure intended to change one’s state of consciousness by means of voluntary shifts in attention
  • a stage between sleep and wakefulness
31
Q

Does meditation produce ASCs ?

A
  • yes 8 stages of meditation (d-ASC)
  • There is a change in network of functional connectivity btw brain regions
  • Some d-ASC can be learned via meditation really fast because they have met experienced
  • other d-ASC need some time beacuse meditation also changes neuronal structures
32
Q

What does d- ASC mean ?

A
  • discrete states of consciousness

- something else then the baseline of consciouness

33
Q

What are some types of ASCs ?

A
  • Spontaneously

- Extreme en

34
Q

What is meant by physiologically induced ASCs ?

A
  • consiciousness changes due to physiological changes (starvation or orgasm)
35
Q

Can mental illnesses produce ASCs ?

A
  • Yes they can
36
Q

Are mentall illness ASCs more psychologically induced or physiologically induced ?

A
  • Mentall illnesess are never just mental. The disorder is linked to feedback loops which connect thoughts emotions and bodily states.
  • Seperation is impossible
37
Q

What is so special regadring ASCs ?

A
  • they are only temporary
  • After a while they return normal state of consciousness
  • that means that disorders have temporary episoded of ASCs (bipolar) -> Psychotic epsiodes and not psychiatric labels
38
Q

What changes druing ASCs ?

A
  • Only the representational consciouness not the phenomenal consiciosuenss
39
Q

What are dreams:

A
  1. dreams are a meaningful reflection of unconscious processes
    + dreams function is related to emotion-regulation, learning, and memory (novel events) consolidation
40
Q

Explaiin the four stages of the contium theory of consciousness:

A
  1. Consciousness during wakefulness (aware of external world)
  2. Consciousness during dreaming (aware of internal world + not recognize own condition)
  3. Nonconsciousness
  4. Intermediates states between them
41
Q

Explain the contium theory of consciousness regarding multiple dimensions:

A
  1. No consciousness
  2. Primary consciousness
  3. secondary consciousness
42
Q

What is meant by primary consciousness ?

A
  • simple awareness of perception and emotion
43
Q

What is meant by secondary consciousness ?

A
  • self-reflective awareness, abstract thinking, metacognition
44
Q

What is the defintion of metacognition ?

A
  • the processes by which individuals monitor and control their own cognitive processes
45
Q

What is a unique differnce between dream consciousness and waking consciousness ?

A
  • They have different origin (causal pathways)

- Dreams may be seen as a purer form of consciousness since it follows less constraints

46
Q

Explain REM sleep:

A
  • High frequency and low amplitude EEG signal
  • Everything else would also be high, in comparisson to NREM!
  • Most likly have vivid dreams (easy to report)
47
Q

Explain NREM sleep:

A
  • Low frequency, high amplitude EEG signal
  • Everything else would also be low in comparisson to REM!
  • Divided in 3 stages
  • Contains more thougt like mentation dreams (not good for a report)
48
Q

Explain lucid dreaming:

A
  • Most rarely
  • people achieve awareness of their own state of consciousnes (metacognition)
  • Mostly in REM
  • High metacognition means u can control ur dreams
49
Q

What is meant by vivid dream?

A
  • Higher imagery quality vividness, bizarrness emotional and self character
  • also more motor content
  • Sensation and perception experience are similar to being awake
  • BUT no metacognition (DLPFC)
50
Q

What is meant by thought like mentations ?

A
  • poor imagery quality
  • no self caharacter
  • Emotionly flat
51
Q

Explain the brain activity in REM sleep:

A
  • large similarity with weakfulness
  • Hyperactivity: occipital temporal visual area and motor cortex abd limbic system
  • Hypoactivity:in inferior parietal cortex and DPLFC
52
Q

Explain the brain activity in NREM sleep:

A
  • Early visual pathway is active and fuiform face area
53
Q

Explain the brain activity in lucid dreaming:

A
  • Increased fronto-parietal activity = which is linked secondary consciounsess
54
Q

Accroding to the multiple dimensions of consciousness theory which consciousness is presented during REM sleep ?

A
  • Mostly primary consciousness
55
Q

Accroding to the multiple dimensions of consciousness theory which consciousness is presented during NREM sleep ?

A
  • Consciousness Varies

- Consciousness does not stop during nREM

56
Q

Accroding to the multiple dimensions of consciousness theory which consciousness is presented during lucid dream sleep ?

A
  • Hybrid:

- primary AND secondary consciousness

57
Q

Regarding the study of consciousness. Why is lucid dreaming so important ?

A
  • It may be the only phenomenon to examine changes in primary and secondary consciousness
58
Q

Name three aspects of consciousness:

A
  • Self determination
  • Planing
  • intention execution
59
Q

What is meant by self determination ?

A
  • subjective experience of acting freely according to one’s wil
60
Q

What is meant by intention exceution ?

A
  • how promptly and determined intentions are executed
61
Q

Compare the three aspects of consciousness to lucid drema non lucid dream and awake sate:

A
  • Self dermination: High in awake and lucid, low in non lucid
  • planing: not existent in lucid and non lucid
  • intention executrion: high in lucid and low in awake and non lucid
62
Q

What has phenomenal similarities to dreams ?

A
  • mental disorders
63
Q

Name some phenomenal similarities between dreams and mental disorders:

A
  • vivid imagery, bizareness, delusional belief of being awake while dreaming
  • bad distinction btw first and third person perspectives
  • there might be a shared mechanism between lucid dreams and psychosis
64
Q

Name some phenomenal differences between dreams and mental disorders:

A
  • judge there menatl disorder as less bizzare eventhough they are just as bizzare
  • psychotic people regarding lucid dreams have more contorl of their internal reality at the expense of external reality
65
Q

What is in general the function of DLPFC ?

A
  • Secondary consciousness
66
Q

What is in general the function of the frontol parietal cicuits ?

A
  • necessary for waking memory, self-reflective awareness
67
Q

What is meant by the principle of perceptual equivalence ?

A
  • We use the same parts of our brains in very similar ways when we think about an image of an object and when we are actually looking at the object.
  • behaviours share similar neural correlates during wakefulness and dreaming (mostly REM)
