Q

what is the difference between james and lange vs. cannon and bard theory of emotion

A

james and lnage believe emotional expression is dependent on feedback from autonomic nervous system
cannon and bard - emotional expression is independent from feedback of autonomic nervous system

Q

why won’t sham rage occur if the hypothalamus is removed

A

the hypothalamus is essential to express anger, therefore connections to hypo are needed to elicit sham rage response

  3. amygdala
21
Q

what is another name for a voluntary smile

A

pap american smile

22
Q

what controls voluntary smiles

A

zygomaticus major

23
Q

what is another name for involuntary smiles

A

duchenne smile

24
Q

what controls involuntary smiles

A

orbicularis oculi - contracts unconciously

25
Q

what shape is the amygdala

A

almond shaped

26
Q

where is the amygdala located

A

tucked in medial temporal lobe

27
Q

which brain is removed to induce kluver bucy syndrome

A

amygdala

28
Q

state some symptoms that occur in kluver bucy syndrome

A
  1. increased oral tendency
  2. visual agnosia
  3. reduced emotional reaction
  4. hypersexuality
  5. hyper metamorphisis
29
Q

why do monkeys who have kluver bucy syndrome no longer fear snakes

A

reduced emotional reaction - fear no longer expressed to snakes

30
Q

define hyper metamorphisis

A

can’t control impulses and react to everything in sight

31
Q

how was fear conditioning induced in little albert

A

child conditioned that exposure to cuddly rabbit would cause fear

32
Q

which brain structure is involved in fear conditioning

A

hippocampus

33
Q

why won’t fear conditioning if you lesion the amygdala

A

responses from the amygdala won’t be elicited

34
Q

from which brain regions does auditory information input to the amygdala

A

auditory cortex

auditory thalamus

35
Q

which brain region elicits faster RT of auditory info to the amygdala and why

A

auditory thalamus has faster RT - older brain region and more evolutionary established

36
Q

which brain region has a key role in fear conditioning

A

hippocampus and medial geniculate nucleus

37
Q

what happens if you lesion medial geniculate nucleus

A

lesioning causes block of fear conditioning

38
Q

which process allows conditioning to occur

A

LTP

39
Q

which brain region did patient SP have removed

A

right amygdala

40
Q

what was the result of patient SP brain damage

A

could not describe fearful situations or expressions

41
Q

what was patient SP still able to do

A

no difficulty on tests of other emotions

42
Q

which disorder is associated with a larger aygdala

A

autism

43
Q

which disorder has lower volumes of activiation in amygdala

A

psychopaths

44
Q

what is the knock on impact of damage to frontal lobes

A

harder to get rid of a fear conditioned response

45
Q

explain why frontal lobe damage affects fear conditioning response

A
  1. damage to frontal lobes - innate response of amygdala is to elicit fear response
  2. unlearning process can’t occur
  3. the amygdala keeps projecting fear response
46
Q

where does the unlearning of information occur

A

frontal higher cog brain functions

47
Q

where would unlearning of information be projected

A

amygdala

48
Q

where are projections from the medial cortex projected to

A

amygdala

49
Q

what was the result of amygdala damage in humans

A

can’t recognise fear in a story
