Q

How come we can have an emotion reaction/response before we’re aware of what’s going on?

becuas their is a connection to the thalamus to cortex to amydala

25
Where is the limbic lobe located?
encircles the upper brain stem (around corpus callosum)
26
what does the limbic system do?
integrates info about emotional content from cortical association areas
27
What happens if you remove an aggressive monkeys amygdala?
they become docile, horny and compulsive
28
What is kluver bucy syndrome?
it is severe temporal lobe damage, specifically to the AMYGDALA that results in visual agnosia, apathy/placidity, disturbance in sexual function, dementia, aphasia, amnesia
29
What are these a part of orbital and medial prefrontal cortex (PFC) nucleus of thalamus amygdala
limbic structure
30
What is the amygdala?
a nuclear mass
31
Where is the amygdala?
buried in the white matter of the temporal lobe, in front of the hippocampus
32
What does the amygdala do?
connects to olfactory bulb cerebral cortex (frontal and association areas of temporal lobe) brainstem and hypothalamus
33
What is considered the "emotional association area"?
amygdala
34
What links the cortical areas the process sensory info to hypothalamus and brainstem effector systems?
amygdala
35
What allows for emotional learning?
amygdala (associative learning)
36
How can you abolish fear response?
remove on amygdala and block visual information from the eye on that side
37
What kind of conditioning is this: | pair tone and foot shock, then tone alone ellicits fear and increased BP and freezing.
associative learning fear response
38
What happens if you infuse NMDA antagonist (preventing LTP) into amygdala during learning?
prevents facilitated learning and long term potentiation
39
What happens to fear response if connection between medial geniculate and amygdala are severed prior to learning?
you dont get it
40
What can damage to the amygdala case?
messed up adaptive responses asymmetric responses non adaptive responses
41
What are the non-adaptive responses?
overactive learned fear response: | PTSD, Depression, Phobias
42
Why does the amydala give you pleasure?
gives emotional coloring of environment learned rewards (anticipation of pleasure) place for drug abuse gives you emotional significance of environment (adapt, size, reproduce)
43
natural rewards elevate (blank)
dopamine
44
What is the neurological basis for pleasure? How does this relate to addiction?
nucleus accumbens | raises your dopamine levels hugely
45
What gives the highest release of dopamine?
amphetamines
46
What gives you the longest release of dopamine?
cocaine
47
What gives you varying amounts of dopamine release with different amounts of consumption, but begins to lessen the amount of release after a certain amount of conusmption.
ethanol
48
What happens after you stop taking cocaine
your dopamine levels fall below normal :(
49
What do drugs do to your brain?
it rewires them
50
(blank) may experience a powerful urger to use when they encounter environmental cues associated with use. (blank) regions of the brain are activated when watching cocaine-related videos.
cocaine abusers | limbic
51
Where do psychopaths have changes in their brain?
in the amygdala
52
How does the orbitofrontal cortex regulate emotion?
the posterior frontal lobe mediates aggression and emotional responsiveness
53
What happens if you have damage to the posterior frontal lobe?
disinhibition
54
Lesion input from amygdala results in what?
decreased rage from disappointed primates
55
What are 2 amydala abnormalities?
kluver-bucy | urbach-wiethe

What do you call it when you separate the tracts from orbitofrontal cortex to amygdala?
lobotomy
61
Is there lateralization of emotions?
yes
62
What does the right hemisphere do?
expession and comprehension of emotional (affective) content
63
Which ear/hemifield is better at detecting emotional nuances of speech/ images and which side of the face may be more expressive of emotion
the left side
64
What side of the brain does this: The understanding and expression of affective (mood) components to speech Relatively more L facial emotional expression
R hemisphere
65
What happens if you damage the right hemisphere?
aprosody unable to read emotional coloring of speech all speech becomes email like
66
What side of the brain is affected if you get aphasia?

depressed | elevated mood
70
Depression more than (blank) the likelihood of dying in the 10 years after a stroke/
triples (treatment with antidepressants may improve survival)
71
Nevada rate for elderly suicide is (blank) percent of national average
300%
72
Is there a genetic component in depression?
yes

5 or more symptoms of 2+ weeks (depressed mood, decreased energy, sleep and appetite changes, memory/concentration changes, thought of death/suicide, guilt, decreased interests, tearfulness)
75
What is the cause of depression?
neurotransmitter structural functional
76
What happens to your blood flow in depression?
in increases to the amygdala (correlates with severity of depression)
77
What moderates negative emotional output fo amygdala?
left prefrontal cortex
78
If your left prefrontal cortex fails what can you get?
depression
79
What happens if you have a left prefrontal cortex?
“Peppy” L PFC: extraversion Levels of cortisol are lower Less reactive to stressors Individual differences measured in infants, adults
80
What happens if you have a low level of L PFC function?
You will be sad
81
What am I talking about: Smaller volume of ventral anterior cingulate in depressed patients (40% smaller) on PET scans with less blood flow Blood flow normalizes with treatment of depression Smaller volume may be related to loss of glial cells cell loss from toxic cortisol levels secondary to stress
characteristics of the left prefrontal cortex in depressed pt's
82
Animals experiencing repeat stress can result in shrinking of (blank)
hippocampus
83
(blank) may shrink in people with recurrent depression
hippocampus
84
hippocampal cell loss may lead to (blank) decline
cognitive
85
Since you can get hippocampul degeneration which will result in depression, how can you get get this dysregulation?
following significant childhood adversity or long term excess cortisol exposure
86
Stress decreased (blank) in hippocampus (could contribute to atrophy and decreased functioning of neurons)
