Q

What are the 2 kinds of fear?

Q

2 pathways for emotional conditioning in response to fear

Q

where do inputs come in from the amygdala

A

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

16
Q

What is the next step in the amygdala?

A
  • the central nucleus

- then goes to the hypothalamus and it does things

17
Q

Disgust

A
  • insular corex/putamen
  • processing and recognition of social cues related to disgust
  • damage (including huntington’s disease) abolishes
18
Q

Anger/rage

A
  • amygdala

- requires dopaminergic input acting at D2 receptors*

19
Q

Anger/rage

A
  • amygdala

- requires dopaminergic input acting at D2 receptors*

20
Q

what is required for the inhibition of anger/rage?

A
  • neocortex
  • vertomedial hypothalamic nuclei
  • septal nuclei
21
Q

step 1 of integrating the inputs?

A
  • Anterior cingulate cortex
  • regulation of affect (“controlling our emotions”)
  • kind of figures out what is going on
22
Q

Step 2

A

-pre frontal cortex

23
Q

2 parts of the pre frontal cortex

A
  • ventromedial PFC** know this one

- dorsolateral PFC

24
Q

Probably roles for PFC

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