Q

Stress and the Hippocampus

A

Cortisol: catabolic hormone

  3. NE levels plasticity - olfactory
  4. Endorphin levels - protein synthesis & memory consolidation
41
Q

A
  • a later: evolving part of the extended amygdala
  • has similar efferent and afferent connections
  • grows in response to maternal behavior
  • sensitive to abstract cues
  • capable of long-term activation
  • appears to play a central role in anticipatory arousal
42
Q

Cortical Release Signs

A

an indication of cortical damage is the reemergence of previously inhibited reflexes

43
Q

Hierarchical Brain, Relationships in PTSD

A
  • Ompfc is smaller in PTSD
  • Amygdala responsivity is correlated with symptom severity
  • exaggerated amygdala response
  • diminished prefrontal activation in response to fearful faces
  • decreased habituation to fearful faces
44
Q

Capgras syndrome

A
  • syndrome of suspecting imposters
  • disconnection between circuits of temporal lobes responsible for face recognition and the ompfc-amygdala axis (which would add the emotional reaction of seeing a loved one
  • the opposite of deja vu
45
Q

Pathways of integration

A
  • Top(cortical) includes left hemisphere, dlpfc, and hippocampus
  • bottom (subcortical_ includes right hemisphere, ompfc, and amygdala
46
Q

as negative affect decreases, amygdala activation ____ while ompfc activation ____

A

decreases; increases

47
Q

simultaneous top-down and left-right inhibition is responsible for

A

repression

48
Q

transcranial stimulation (TMS)

A

-stimulates and inhibits neural firing to treat depression

49
Q

Ompfc vs dmpfc

A

ompfc- emotional

dmpfc- cognitive

50
Q

Prejudice and ompfc/ dmpfc

A
  • when people make decisions based on implicit biases, ompfc and amygdala become more active
  • when people make decisions incongruent with prejudice, dlpfc becomes more active
51
Q

in higher states of arousal, hippocampal and amygdala networks becomes dissociated. This results in:

A

a disconnection between visceral-emotional (amygdala) and declarative-conscious (hippocampal) processing

52
Q

Functions of narratives (6)

A

1) ground our experiences in a linear framework
2) remember sequences of events in problem solving
3) allow a context for movement to self-definition
4) serve as blueprints for emotion, behavior, and identity
5) provide for affect regulation when under stress
6) keep goals in mind and establish sequences of goal attainment

53
Q

Why does journaling about emotional issues have a positive effect?

A

it increases prefrontal activation, downregulating the negative emotional activation of the amygdala

54
Q

3 Levels of Language Processing

A

1) Reflexive social language
2) Internal dialogue
3) Language of self-reflection

55
Q

Reflexive social language

A
  • a stream of words that maintains ongoing social relatedness and communication
  • function of left hemisphere
56
Q

Internal dialogue

A
  • the conversations we carry on with ourselves inside our heads
  • the primary way that right hemisphere processing participates in conscious awareness
  • we hear in our heads the supportive or critical voices our parents implanted early in life
57
Q

Language of self-reflection

A
  • when we reflect on RSL and internal dialogue
  • in self-reflection, we learn that we are not only our social reflexes (RSL) plus the voices that haunt us (internal dialogue) but also the one that can observe, listen, and judge what we hear these voices say
  • the deepest level of this is meditation
58
Q

Define flashback

A
  • intense revisualization of the trauma scene
  • stereotyped and repetitive
  • more detailed and perceptually based
  • products of nonconscious information associated with rapid, automatic transmission
59
Q

Define ordinary/autobiographical memory

A
  • recalled in narrative form

- usually episodic recollections from an individual’s life

60
Q

Define and discuss verbally accessible memory

A
  • supports ordinary autobiographical memories
  • access autobiographical knowledge base so that trauma is represented within a complete personal context
  • edited and interactive
  • comprises past, present and future
61
Q

Define and discuss situationally accessible memory

A
  • supports specific trauma related dreams & flashbacks
  • retrieved automatically not strategically
  • no interaction with autobiographical memories
62
Q

What 3 aspects differentiate flashbacks from autobiographical memories

A
  1. automatic mode of retrieval
  2. High level of perceptual detail
  3. Distortion of subjective time
63
Q

Define Somatic Markers

A
  • Signals in the body that influence the process of response to stimuli
  • Associations between reinforcing stimuli that induce associated physiological affective state
  • Directs attention towards more advantageous options, which usually simplifies the decisions
64
Q

What regions of the brain affect the hypothesis

A

Ventromedial Prefrontal cortex and the Amygdala

65
Q

What makes it hard to plan and make decisions (damasio)?

A

Damage to the Ventromedial Prefrontal Cortex (focal damage to the frontal lobe) - region in the brain that processes human reasoning and decision making

66
Q

The two circuits of sensory input that reach the amygdala are?

A
  • thalamus: serves rapid responses during survival decisions based on a minimum of information
  • loops through the cortex and hippocampus before reaching the amygdala: slower, adds cortical processing (context and inhibition) to appraise ongoing perceptions and behaviors
