Facilitate behaviours by providing quick mobilization of energy for movement
Facilitate behaviours by providing quick mobilization of energy for movement
This is known as…?
Autonomic emotional response pattern
What is a hormonal emotional response pattern?
Reinforce autonomic responses via brain mechanisms
Reinforce autonomic responses via brain mechanisms
This is known as…?
Hormonal emotional response pattern
True or False?
Behavioural, Autonomic and Hormonal emotional response patterns are organised by the same neural systems
False
Behavioural, Autonomic and Hormonal emotional response patterns are organised by different neural systems
The integration for fear is controlled by the …?
Amygdalae
Amygdalae controls…?
The integration for fear
What are the 3 components of the amygdala in fear processing?
1) Lateral nucleus
2) Basal Nucleus
3) Central Nucleus
What is the Lateral Nucleus?
Main input nucleus in fear processing
Where does the Lateral Nucleus send its projections?
Sends internal and some external projections
Where does the Basal Nucleus send its projections?
Sends internal and limited external projections
What is the central nucleus?
Main output nucleus
Where does the Central Nucleus send its projections?
Sends projections to various brain regions
e.g. hypothalamus, brain stem, etc.
When a threatening nucleus is present, which nucleus in the amygdala is activated?
Central nucleus
Which nucleus in the amygdala is the main output nucleus?
Central nucleus
Which nucleus in the amygdala is the main input nucleus?
Lateral nucleus
Which nucleus in the amygdala sends internal and some external projections?
Lateral nucleus
Which nucleus in the amygdala sends internal and limited external projections?
Basal nucleus
Which nucleus in the amygdala sends projections to various brain regions?
Central nucleus
What happens when the Central Nucleus of the Amygdala is damaged?
Reduces or abolishes a wide range of emotional responses
When the Central Nucleus of the Amygdala is damaged, it reduces or abolishes a wide range of emotional responses.
What happens to animals in terms of fear?
Animals no longer show fear when faced with stimuli that are paired with aversive events
Monkeys with amygdala lesions are not afraid of snakes
True or False?
True
When the Central Nucleus of the Amygdala is damaged, it reduces or abolishes a wide range of emotional responses.
What happens to animals in terms of tamed actions?
Animals act more tamely when handled by humans
They have lower stress levels in their blood and are likely to develop stress-induced illnesses
Which nucleus in the amygdala is responsible for the establishment of a conditioned emotional response?
Lateral Nucleus
The lateral nucleus in the amygdala is responsible for the establishment of a conditioned emotional response.
How does this work? List 2 steps
1) Neurons in the Lateral Nucleus communicate with neurons in the Central Nucleus
2) The Central Nucleus communicates with the regions that are responsible for the behavioural, autonomic and hormonal components of the conditioned emotional response
1) Neurons in the Lateral Nucleus communicate with neurons in the Central Nucleus
2) The Central Nucleus communicates with the regions that are responsible for the behavioural, autonomic and hormonal components of the conditioned emotional response
This is known as…?
Conditioned emotional response by the Lateral Nucleus
Define extinction
A learned process that the conditioned stimulus is no longer followed by an aversive stimulus
A learned process that the conditioned stimulus is no longer followed by an aversive stimulus
This is known as…?
Extinction
True or False?
Extinction is the same as forgetting
False
Extinction is when a behaviour is inhibited but not forgotten (it can be retrieved the same way one had learned that particular behaviour)
Which part of the brain is responsible for extinction/removing associations or inhibiting emotional responses?
The ventromedial prefrontal cortex (vmPFC)
What is the ventromedial prefrontal cortex (vmPFC) responsible for?
Extinction/removing associations or inhibiting emotional responses
True or False?
Stimulation of the vmPFC produces conditioned emotional responses
False
Stimulation of the vmPFC inhibits conditioned emotional responses
What activates vmPFC neurons?
Extinction training
Extinction training activates …?
vmPFC neurons
True or False?
Lesions to the vmPFC improve extinction
False
Lesions to the vmPFC impair extinction
What happens to extinction when there is a lesion to the vmPFC
Extinction becomes impaired
What is a phobia?
Unreasonable fear associated with a specific object or situation
Unreasonable fear associated with a specific object or situation
This is known as…?
Phobias
What are the 4 symptoms of phobias?
1) Avoidance of object or situation
2) Persistence of fear over time
3) Significant distress associated with the fear or avoidance
4) Awareness that phobia is irrational or unreasonable
What do vmPFC activations predict in terms of therapy?
Predicts which therapy will work better to help people with certain phobias/ exposure therapy outcome
True or False?
Emotions are mono-component phenomena
False
Emotions are multi-component phenomena
True or False?
Amygdala is involved in fear processing
True

Lateral Nucleus is the most important nucleus in fear processing
False
Central Nucleus is the most important nucleus in fear processing
True or False?
Basal Nucleus is the most important nucleus in establishing a conditioned emotional response
False
Lateral Nucleus is the most important nucleus in establishing a conditioned emotional response
True or False?
Ventromedial Prefrontal Cortex is activated by extinction training
