Question 2

What does the limbic system control?

Answer 2

• emotional behavior

- motivational drives

Question 3

what does the hypothalamus do?

Answer 3

• emotional experience

- links the physiological responses to the emotions*

Question 4

Olfactory area

Answer 4

-linked with emotion and smell

Question 5

Thalamus

Answer 5

• anterior nucleus part of papez circuit

- inputs and outputs… relaying things

Question 6

Basal ganlia

Answer 6

• nucleus accumbens= plesure

- putamen= disgust

Question 7

hippocampus

Answer 7

-memory

Question 8

Amygdala

Answer 8

• fear and anger

- role in learning and memory

Question 9

cingulate cortex

Answer 9

• many of these neurons show after-discharge!!!

- can’t let it go

Question 10

what was that important thing she said about emotion?

Answer 10

-it appears that the neural circuits for recognizing emotion in others are also involved in producing that emotion in ourselves

Question 11

what is the deal with mirror neurons?

Answer 11

-when someone smiles, we smile

Question 12

What are the 2 kinds of fear?

Answer 12

• innate (unconditioned): requires no experience, olfactory clues (pee)
• learned (condition): we learned it from experience.. most common in humans, can be indirect… horror movie moneymaker

Question 13

What does the amygdala do again?

Answer 13

-process and recongize the social cues related to fear

Question 14

2 pathways for emotional conditioning in response to fear

Answer 14

• direct thalamo-amygdaloid (early response)

- indirect thalamo-cortical-amygdaloid (late response)

Question 15

where do inputs come in from the amygdala

Answer 15

-thalamus and the cortex via the lateral nucleus of the amydala is what actually integrates things

Question 16

What is the next step in the amygdala?

Answer 16

• the central nucleus

- then goes to the hypothalamus and it does things

Question 17

Disgust

Answer 17

• insular corex/putamen
• processing and recognition of social cues related to disgust
• damage (including huntington’s disease) abolishes

Question 18

Anger/rage

Answer 18

• amygdala

- requires dopaminergic input acting at D2 receptors*

Question 19

Anger/rage

Answer 19

• amygdala

- requires dopaminergic input acting at D2 receptors*

Question 20

what is required for the inhibition of anger/rage?

Answer 20

• neocortex
• vertomedial hypothalamic nuclei
• septal nuclei

Question 21

step 1 of integrating the inputs?

Answer 21

• Anterior cingulate cortex
• regulation of affect (“controlling our emotions”)
• kind of figures out what is going on

Question 22

Step 2

Answer 22

-pre frontal cortex

Question 23

2 parts of the pre frontal cortex

Answer 23

• ventromedial PFC** know this one

- dorsolateral PFC

Question 24

Probably roles for PFC

Answer 24

• reward processing
• integration of bodily signals
• top down regulation: delayed gratification
