1

Where do we find emotions?

in the amygdala

2

What is a major structure leading to patterns of physiological change which pause when emotions occur?

amygdala

3

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

4

The innermost part of the brain is about (blank)

survival

5

What do emotions do for us?

help us respond to important situations and to convey our intentions to others

6

The voluntary smile is driven by?

motor cortex, pyramidal tracts

7

What is the involuntary smile driven by?

motor areas in ant cingulte, extrapyramidal, reticular activating system

8

What is your emotional response driven by?

subjective
autonomic

9

What parts of your brain contribute to your emotional response?

structures
pathways

10

what is the emotional motor system?

subective experience-> visceral and somatic motor response

11

What is a primary emotion experienced by all social animals that creates a visceral motor and somatic motor response?

fear

12

How do you measure fear in animals?

heart rate and blood pressure
salivation
respiratory rate
scanning
startle
urination/defecation
freezing

13

What is the brains shortcut for emotions?

it can directly hit up the amygdala from the thalamus and bypass the visual cortex

14

how do humans respond to fear?

heart pounding or racing
dry mouth
pale skin
respiratory rate
hypervigilance
increased startle
urination/diarrhea
apprehensive expectation

15

What are the brain structures that mediate emotion?

hypothalamus
limbic system (limbic cortex, amygdala)
brainstem
nucleus accumbens
prefrontal cortex

16

What does the hypothalamus function in?

light dark cycle
temperature regulation
neuroendocrine
integral in emotion and sexual behaviors

17

What do the removal of the cerebral hemispheres show?

showed that the hypothalamus integrated emotions and behaviors

18

What kind of emotion is experienced with ablation of just the cerebral hemispheres? Of the cerebral hemispheres AND the hypothalamus?

rage, attack with just the hemispheres

Docility with the hemispheres and hypothalamus

19

What is the the route information takes to go through the hypothalamus?

input form cortex (relatively unprocessed)
output to brainstem's reticular formation

20

What is the link between higher cortical activity and the "lower" systems that control emotional behavior?

limbic system

21

What makes up the limbic system?

the limbic lobe and deep lying structures (amygdala, hippocampus, mamillary bodies)

22

What are considered the deep lying structures of the limbic system?

amygdala, hippocampus, mamillary bodies

23

What allows you to have the duchenne smile?

cingulate gyrus

24

What is this:
primitive cortical tissue with a cingulate gyrus and parahippocampal gyrus

limbic lobe

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
