huntingtons

Question 5

part of papez circuit, plays role in learning/memory

Answer 5

hippocampus

Question 6

what plays a role in fear and anger

and what input required

Answer 6

amygdala

dopaminergic input acting at D2 receptors

Question 7

this part of brain has after-discharge, so continue to fire after stimulus, still feel emotion over time. can’t let something go even after it is done

Answer 7

cingulate cortex

Question 8

innate fear in animals associated with

Answer 8

associated with olfactory cues

Question 9

innate fear in humans from

Answer 9

falling and loud noises

Question 10

other type of fear

Answer 10

learned fear

Question 11

emotional conditioning in response to fear, 2 pathways

Answer 11

direct thalamo-amygdaloid (early response)
TA
indirect halamo-cortical-amygdaloid (late response)
TCA

Question 12

inputs from the thalamic and cortex arrive at the ____ of the amygdala which does what and sends the signal where, then the signal is sent where

-basically whole fear circuit

Answer 12

lateral nucleus which integrates the inputs and sends them to the basal and intercalated nuclei for additional processing then all this is sent to the central nucleus of amygdala which then decides what response are required and relays info appropriately

Question 13

what is strongly activated when recalling sad events

Answer 13

ACC had SAD outing in tourney

lower anterior cingulate cortex

Question 14

neuroanatomical basis for punishment and avoidance substrates

Answer 14

lateral posterior hypothalamus
dorsal midbrain
entorhinal cortex

avoid DMing Lauren p Hale, for Extra Credit

Question 15

inhibition of anger/rage requires what

Answer 15

neocortex
ventromedial hypothalamic nuclei
septal nuclei

new VMH (awards) suck nuts sept I wont get mad about it

Question 16

anterior cingulate cortex 2 regions

Answer 16

ventral = affective (controlling our emotions)

dorsal = cognitive

Question 17

integrating the inputs starting with ACC

Answer 17

integrates visceral, attentional, and emotional input and regulates affect, relays info to the prefrontal cortex

Question 18

two divisions of prefrontal cortex

first

Answer 18

ventromedial which receives input from THAD

temproal visual association area
hippocampus
amygdala
dorsolateral prefrotnal cortex

Question 19

second division of prefrontal cortex

Answer 19

dorsolateral which gets input from mcc

motor areas
cingulate cortex
cortical association areas

Question 20

3 probable roles of pre-frontal cortex

Answer 20

reward processing (orbitofrontal) with amygdala

integration of bodily signals (ventromedial prefrontal) gut feeling

top down regulation: especially towards delayed gratification

RIT this down, there are 3 roles
