Question 1

3 roles of hypocampus

Answer 1

1. encodes, consolidates and retrieves explicit memories.
2. transfers newly encoded explicit memories to relevant parts of the brain for permanent long-term storage
3. interacts with the amygdala to link emotions to explicit memories

Question 2

1 role of neocortex

Answer 2

1. stores explicit memories for a long time in relevant parts of brain.
   eg. iconic/visual memories kept in occiptal lobe

Question 3

3 roles of the amydgala

Answer 3

1. regulation of emotions such as fear and aggression
   2.store memories of events and emotions so that you can recognise similar situations in the future (helps with survival)
   3.encoding implicit memories to do with emotions

Question 4

in the amydgala, storage of memory is influenced by

Answer 4

the initiation of the flight-or-fight-or-freeze response and stress hormones

Question 5

2 roles of the basil ganglia

Answer 5

1. formation (or encoding) of implicit procedural memory, specifically habits
   2.encode fine motor control (relating to a sequence of goal-directed behaviour) so that it can be performed in a fluid manner

Question 6

how does the basil ganglia encode implicit memorys, particullary habits

Answer 6

associating movement with reward or reinforcement.
eg. take a dif route home and get home quicker

Question 7

2 roles by cerebullum

Answer 7

1.encoding and temporary storage of implicit procedural memories for motor skills, (ones created by classical conditioning)
2.coordinating fine muscle movements and regulating posture and balance

develop certain conditioned reflexes, such as associating a beep with the puff of air that immediately follows
