Flashcards in Neurobiological Basis of Emotion, Cognition, Behavior and Relations Deck (23):
1

Effect: Glutamate

Learning and Memory

2

Effect: Dopamine

Reward, motivation, pleasure, euphoria
Control of Fine Motor

3

Parkinson's Disease results from?

Atrophy/Blockage of Dopamine

4

Effect: Serotonin

Unusual states of pleasure

5

What three organs mainly respond to stress?

Hypothalamus
Pituitary
Adrenal Cortex

6

What does the Hypothalamus produce under stress?

Corticotropic Releasing Hormone

7

What does the Pituitary produce under stress?

Converts precursor molecules to Adrenocorticotropic Hormone, Opioids and Melatonin

8

What does the Adrenal Cortex produce under stress?

Glucocorticoids

9

What inhibits the hypothalamus from producing more CRH and Pituitary from producing ACTH?

Glucocorticoids

10

What is secreted during sleep?

Growth Hormones

11

What are the different Dopamine receptors?
Where are they located?

D2-4 in the Nucleus Accumbens (Evokes Pleasure)
D1, D5 in the Frontal Lobe (For Pleasure)

12

Function: Cortical Memory

Long term storage of pleasurable experiences

13

What part of the brain perceives fear?

Amygdala

14

Fear Pathway

1. Thalamus receives signals and sends to both amygdala and cortex
2. Amygdala registers danger
3. Amygdala triggers fast response
4. More considered response based on cortical processing

15

[Anger]

Where is it processed?

Thalamus

16

[Anger]

What is responsible for autonomic response and predatory aggression?

Lateral Thalamus

17

[Anger]

Function: Periaqueductal Gray Matter

Responsible for coping behavior and defensive aggregation

18

Thinking is a function of?

Frontal Lobe

19

Steps for Memory

Encoding
Storage
Retrieval

20

What does sleep enhance?

Glutaminergic Activity for long-term memory storage

21

Function: Hippocampus

Consolidation of Memory
Spatial Consciousness
Storage of Verbal Memory

22

Define: Social Cognition

Ability of organisms to understand others as being like themselves who have intentions and mental lives of their own

23

Define: Mirror Neurons

Structures that become active when a person observes an act being executed by another
