25
Stimulating GABA neurons in the medial amygdala of the posterior dorsal division causes what behaviors ?
Try to have sex and extreme rage
26
Stimulating Glutamate neurons in the medial amygdala of the posterior dorsal division causes what behaviors ?
disengage socially and start grooming themselves
27
The 25 unique emotion blends result in what type of expressions ?
Multimodal behavioural expressions involving voice, touch, posture, gaze, and head/body movement
28
What are the 3 steps of the theory of emotions ?
1. Perception of emotion-eliciting event/stimuli 2. Subjective feelings of emotion 3. Behavioral and physiological responses
29
People with damage to what peripheral structure feel emotions less intensely ?
Spinal cord
30
Reduction in emotional experiences correlated with how much _____the people had lost
Sensation
31
Could people with spinal cord damage still have behaviors linked to emotions ?
People could exhibit behaviors but not feel emotions
32
What are the 3 steps of the James-Lange theory ?
1. Perception of emotion-eliciting event 2. Collection of behavioural and physiological responses are triggered by the brain unconsciously 3. Feedback from the peripheral nervous system to the brain triggers subjective feelings of emotion (e.g., fear).
33
According to James Lange, an emotion is a 1 to 1 mapping to ____ responses
Body
34
Does interfering with the muscular movement associated with a particular emotion decreases people's ability to experience that emotion ?
Slightly
35
What type of drugs can eliminate the fight or flight response ?
Beta blockers
36
Do beta blockers eleminate the emotion ?
Beta blockers only eleminate the behavior
37
Do our internal organs respond to emotions quickly ?
No because they are relatively insensitive to emotions
38
True or false : cutting the sensory nerves between the internal organs and the central nervous system abolishes emotional behaviour in animals
False
39
True or false : injecting hormones or artificially activating the autonomic nervous system cannot create emotions
True
40
The arousal of the brain changes the cognitive assessment of the emotion in the ___ cortex
Precortex
41
Where is the cingulate cortex ?
In the lymbic system, it overlies the corpus callosum.
42
In what lobe are located the hippocampus and amygdala ?
The temporal lobe of the cerebral cortex
43
The hippocampus is critical for...
Explicit memory formation
44
The amygdala is critical for...
Feeling and recognizing emotions, particularly fear
45
What surgery did patient SP receive ?
Bilateral amygdalectomy to treat a seizure disorder
46
What emotion did patient SP no longer feel ?
Fear
47
Could patient SP still recognize people in photographs ?
Yes, only not identify their fear (same in pictures of herself)
48
What other emotions did she have difficulty recognizing to a lesser extent ?
Disgust, sadness, happiness
49
Patient SP could still detect which 2 emotions ?
Anger and surprise
50
People with no amygdala...
Have no concept of personal space, do not understand social situations, put themselves in dangerous situations.
51
What part of the face do we spontaneously look at to identify someone's emotion ?
The eyes
52
When shown faces, patient SM (bilateral amydgala damage) does not look at...
The eyes. She had to be taught to do so to identify emotions.
53
What part of the amygdala regulates emotional responses, especially fear ?
Central nucleus
54
Lesions of the central nucleus reduce/eliminate ____and ____fear responses
Both innate and learned
55
What fear is normal in people with bilateral amydgala damage ?
Fear of suffocation
56
What creates the fear of suffocation ?
The medulla detects the raising levels of CO in the blood.
57
Stimulation of the central nucleus of the amygdala causes...
Fear, anxiety, agitation
58
Persistent stimulation of the central nucleus of the amygdala can cause...
Stress induced illnesses like ulcers
59
What activates the central nucleus of the amygdala ?
Viewing threatening stimuli or fearful faces
60
The central nucelus of the amygdala receives information from...
Superior colliculi, visual thalamus, and visual association cortex
61
Patients with damage to primary visual cortex or visual association cortex may have no conscious awareness of looking at a person’s face, but they may still show...
Amygdala activity in response to viewing faces mimicking the presented facial reaction (happy or fearful face).
62
What other areas of the brain activate when we look at emotional faces ?
Somatosensory cortex, insular cortex, premotor cortex, and cingulate cortex.
63
What hemisphere seems more involved in recognizing emotions ?
The right hemisphere (especially in the lateral fissure)
64
What is the role of the Ventromedial Prefrontal Cortex (vmPFC) ?
Regulating expressions of emotions
65
Is the vmPFC inhibitory or excitatory ?
Usually inhibitory
66
When learned fear responses are extinguished, connections between the vmPFC and amygdala are strengthening or reducing ?
Strengthening
67
Lesioning the vmPFC and amygdala selectively disrupts...
Extinction learning and restores the original fear memory.
68
The original fear memory is in the...
Medulla
69
The learned fear memory is in...
The prefontal cortex
70
People with damage to their vmPFC often struggle to...
Control their emotions and act with adult maturity
71
This is the last part of the brain to be myelinated in teen years
Prefrontal cortex
72
Interactions between the prefrontal cortex and amygdala regulate ____ responses.
Emotional
73
What brain damage was Phineas Cage victim of ?
Damage to the ventromedial prefrontal cortex (vmPFC)
74
After his injury, Phineas Cage was...
Childish, irresponsible and thoughtless of others
75
Damage to the vmPFC weakens behavioral control and impair decision-making; but not ...
Cognitive abilities
76
