Neurobiological Basis of Emotion, Cognition, Behavior and Relations Flashcards
Effect: Glutamate
Learning and Memory
Effect: Dopamine
Reward, motivation, pleasure, euphoria
Control of Fine Motor
Parkinson’s Disease results from?
Atrophy/Blockage of Dopamine
Effect: Serotonin
Unusual states of pleasure
What three organs mainly respond to stress?
Hypothalamus
Pituitary
Adrenal Cortex
What does the Hypothalamus produce under stress?
Corticotropic Releasing Hormone
What does the Pituitary produce under stress?
Converts precursor molecules to Adrenocorticotropic Hormone, Opioids and Melatonin
What does the Adrenal Cortex produce under stress?
Glucocorticoids
What inhibits the hypothalamus from producing more CRH and Pituitary from producing ACTH?
Glucocorticoids
What is secreted during sleep?
Growth Hormones
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)
Function: Cortical Memory
Long term storage of pleasurable experiences
What part of the brain perceives fear?
Amygdala
Fear Pathway
- Thalamus receives signals and sends to both amygdala and cortex
- Amygdala registers danger
- Amygdala triggers fast response
- More considered response based on cortical processing
[Anger]
Where is it processed?
Thalamus
[Anger]
What is responsible for autonomic response and predatory aggression?
Lateral Thalamus
[Anger]
Function: Periaqueductal Gray Matter
Responsible for coping behavior and defensive aggregation
Thinking is a function of?
Frontal Lobe
Steps for Memory
Encoding
Storage
Retrieval
What does sleep enhance?
Glutaminergic Activity for long-term memory storage
Function: Hippocampus
Consolidation of Memory
Spatial Consciousness
Storage of Verbal Memory
Define: Social Cognition
Ability of organisms to understand others as being like themselves who have intentions and mental lives of their own
Define: Mirror Neurons
Structures that become active when a person observes an act being executed by another
