The process of fear learning
The low road is a connection between which two brain parts? [2]
The high road is a connection between which two brain parts? [2]
Low road:
* Thalamus to amygdala
High road:
* Thalamus to sensory cortex to amygdala
Toxoplasma gondii is a parasite that exploits this role of which part of the limbic system?
Hippocampus
Amygdala
Parahippocampal gyrus
Posterior cingulate gyrus
Anterior cingulate gyrus
What effect does this have on a person? [1]
Toxoplasma gondii is a parasite that exploits this role of which part of the limbic system?
Hippocampus
Amygdala
Parahippocampal gyrus
Posterior cingulate gyrus
Anterior cingulate gyrus
Toxoplasma gondii parasite linked to risky business behavior?
What is Urbach-Wiethe disease? [1]
Urbach-Wiethe disease:
* rare recessive genetic condition that causes calcium to build up into the amygdala until it wastes away
What does latest research about amygdala suggest about its role? [2]
Instead of being responsible for feeling fear or other emotions, amygdala is responsible for:
- detecting emotional information related to threats and automatically orienting towards the location of potential threats
- directing other brain areas to pay attention to it in the proper way
Can basic emotions be distinguished from a neural perspective? [1]
Each emotion is associated with an array of smaller and larger patches of brain activity: there are different hotspots associated with each emotion
BUT
Rather than being specialized for one type of emotion, individual brain regions often contribute to multiple emotions
Damage to the amygdala causes which three consequences? [3]
Interpreting or understanding stimuli with emotional consequences
The learning of fear responses
Retention of fear responses previously learned
Describe the function of the hippocampus [2]
- Labels new experiences with place and time and other parameters
- This is important info for ‘labelling’ memories to allow them to be stored in the cortex and retrieved when needed.
- The hippocampus is essential for the consolidation of information from short-term to long-term memories
- Doesn’t store information itself. Without the hippocampus, new memories are unable to be stored in long-term memory.
State the exact location the hippocampus [1]
medial region of the temporal lobe
What are the two forms of amnesia? [2]
Retrograde Amnesia: Describes amnesia where you can’t recall memories that were formed before the event that caused the amnesia.
Anterograde Amnesia: Describes amnesia where you can’t form new memories after the event that caused the amnesia
State the type of learning & memories that the hippocampus is responsible for [3]
Declarative (explicit) memory:
* Episodic memory: life events
* Semantic memory: general facts and knowledge
Which structures are mostly associated with the emotional limbic system? [2]
Which structures are mostly associated with the memory limbic system? [2]
Do they behave independently or are they connected? [1]
Emotional limbic system:
* orbitofrontal cortex
* Amygdala
* associated structures
Memory limbic system:
* Hippocampus & Papez circuit
Act independently but they share cortical nodes when an emotional state is connected to an episodic memory episode
Which areas of the brain connects rewards to appropriate actions? [3]
Anterior cingulate gyrus
Subgenual anterior cingulate gyrus
Orbitofrontal cortex
Which area of the brain is responsible for representation of values of primary re-inforcers and various stimuli, events or goals? [1]
Orbitofrontal cortex
What is the role of the insula? [1]
Emotional aspect of risk taking
