Q

What role does the cingulate cortex play in the limbic system?

-what about anterior cingulate coretx

A

After discharge: A role in why emotions continue after initial event

Ant cingulate cortex - whether you show emotion/not
-integrate info, regulate affect, detect conflict btn fxnal and new info
=Higher level control

Q

After inputs from both fear pathways arrive at the lateral thalamus of the amygdala, where do these inputs travel to?

A

Basal and intercalated nuclei of the amygdala for additional processing

17
Q

After traveling to the basal and intercalated nuclei of the amygdala, where does the information travel to?

A

Central nucleus of amygdala

18
Q

Where does the central nucleus of amygdala send information to?

A

Hypothalamus to create physiologic response

19
Q

What happens if a person presents with a damaged amygdala?

A

Fear is not perceived and there is no conditioning to fear

20
Q

What receptors does “anger” use?

A

D2 receptors at amygdala

21
Q

What can inhibit display of anger?

A

Neocortex
Ventromedial Hypothalamic Nuclei
Septal Nuclei

-does not affect experience

22
Q

What is avoidance?

A

Prevents behaviors that have short term rewards but long term negative consequences

23
Q

What are the anatomical structures that deal with avoidance?

A

Lateral posterior hypothalamus
Dorsal midbrain
Entorhinal cortex

24
Q

What are the anatomical structures that deal with sadness?

A

Lower sector of anterior cingulate cortex

25
Q

What are the anatomical structures that deal with disgust?

A

Putamen and insular cortex

26
Q

What are the anatomical structures that deal with surprise?

A

Parahippocampal gyrus

27
Q

What does the ventral region of the anterior cingulate cortex do?
