1

parts of the papez circuit actually involved in emotions

cingulate cortex and the hypothalamus

2

Areas of the limbic system involved in emotional processing

amygdala, anterior and mid-cingulate cortex, mediodorsal nucleus of the thalamus and prefrontal cortex.

3

Primary emotions are reflexive and involve the (3)

amygdala, hypothalamus, and PAG

4

what primarily drives primary emotions?

 

the amygdala ---- which gets input from the auditory pathway (or visual) via the thalamus as well as directly from the auditory pathway. 

5

___ emotions are conscious 

Secondary

6

secondary emotions and involve the ___

cortical limbic structures

7

Stimulation of the___ with norepinephrine induces the fight or flight response

 dorsolateral portion of the PAG

8

. Stimulation of the ___ portion of PAG with norepinephrine leads to  hypoactivity

ventral

9

Since the ___ nuclei project to the PAG, you can also stimulate the ___ nuclei for the same effect. 

hypothalamic

10

You need the ___ and ___ to regulate emotions.  

 

If you get a stroke or tumor to either one of these regions you lose control of your emotions and can result in sham rage (excessive rage without external control)

hypothalamus or the PAG

11

. Only th___ and ___ cingulate cortex play a role in emotional processing. 

cingulate cortex

12

is the posterior cingualte cortex ivnovled in emotion?

no

13

. It may be useful to think of serotonin as mood ___ 

altering

14

. It may be useful to think of norepinpehrine as mood 

elevating

15

what is included in the papez circuit

16

___ is the synapse site of the limbic system in the thalamus

mediodorsal n. 

17

primary emotions are linked with ___ reflexes

autonomic 

18

If a monkey’s temporal lobe / amygdala was removed, the animal became (4)

1. docile


2. hyperoral

3. hypersexual

4. and ate inappropriate items.

19

Urbach-Wiethe disease = what is the cause and what are the sx?

calcification & loss of amygdala
 

1. no fear response

2. can’t recognize fear in faces

3. risky behaviors

20

Fear response involves direct connections from 

thalamus to amygdala

21

 Shown by auditory-foot shock conditioning experiment. Even if amygdala/
auditory cortex connection was cut,

fear was still present

22

Amygdala connects to __ and __ for fight-or-flight response

PAG and LC

23

Stimulation of ___ PAG = fight-or-flight,

Dorsal

24

lesion of Dorsal PAG

affective defense & "sham rage"

 

25

lesion fo ventral pag

quiet, biting

26

All major emotion structures are connected to
the __

 PAG

27

The PAG regulates ANS via

soliary n.

dorsal mtoor fo vagus

IML

28

The hypothalamus-pituitary axis (HPA) is driven by the (3)

amygdala, limbic cortex, & locus
coeruleus

29

Amygdala / Insula / Limbic Cortex (ACC) --> Paraventricular Nucleus (PVN) of hypothalamus -->

CRH

30

the amygdala projects to which cingulate cortex?

the ACC and anterior MCC
