1) Declarative
2) Procedural.

What is the difference between declarative and procedural memory?
Definition
Declarative is a record of fact accessible to the consciousness. Procedural involves skills and behaviours.
Term
Which areas of the brain are responsible for procedural memory, skeletal musculature and emotional responses?
Definition
Procedural memory: striatum
Skeletal musculature: cerebellum
Emotional responses: amygdala
Term
What is retrograde amnesia?
Definition
Missing memories before the trauma.
Term
What is anterograde amnesia?
Definition
Failing to incorporate new memories.
Term
Where are memories distributed?
Definition
Throughout the neocortex. If reliant on only one sense then they are located in the related cortical area.
Term
What is the role of the medial temporal lobe?
Definition
Declarative memory.
Term
What is Kluver-Bucy syndrome?
Definition
Frontotemporal dementia. It results in:
1) Hyperphagia
2) Hypersexuality
3) Innappropriate emotional behaviour
4) Probable visual agnosia.
Term
What kind of amnesia would you expect in MTL damage?
Definition
Anterograde amnesia.
Term
What does damage to the entorhinal cortex result in?
Definition
Loss of long term memory.
Term
What is the hippocampus important for?
Definition
1) Spatial memory
2) Associative learning (bringing together different sensory inputs).
Term
Which regions of the medial temporal lobe are most important for memory?
Definition
1) The rhinal cortex
2) The hippocampus
3) The amygdala.
Term
What are the key symptoms of korsakoff's syndrome?
Definition
1) Marked anterograde and retrograde memory disturbance
2) Confabulation
Term
What is the cause of Korsakoff's syndrome?
Definition
Thiamin deficiency, secondary to malnutrition in chronic alcoholism.
Term
Where are lesions commonnly found in Korsakoff's syndrome?
Definition
The dorsomedial thalamus and mamillary bodies.
Term
What is the relationship between Parkinson's and stimulus-response habits?
Definition
Parkinson's damages the substantia nigra (input to the striatum) and patients cannot form stimulus-response habits.
Term
What is the difference between primary and secondary dementia?
Definition
1) Primary: protein deposit problems cause neuronal death
2) Secondary: associated with systemic or neurological disease.
