1

Where are memories formed?

Limbic system

2

Where are memories stored?

Association areas

3

What comprises the limbic system?

Hypothalamus
Hippocampus
Cingulate gyrus
Amygdala

4

What does electrical stimulation of areas in the brain create?

Reward and punishment areas

5

Why are reward and punishment areas important?

Gives a risk significance

6

How is the hippocampus involved in memory?

Sensory information goes through it, relays information to other limbic systems

7

What will have to the memory of a person with bilateral hippocampal damage?

Have immediate and intact long term memory
Unable to form new memories
Reflexive memory (motor skills) intact

8

What are the different types of memory?

Immediate/ sensory memory
Short term memory
Intermediate long term memory
Long term memory

9

What happens to a short term memory if it is deemed significant?

Consolidation in long term memory storage

10

What is anterograde amnesia?

Inability to recall events following the injury. Can be short lived or permanent

11

What is retrograde amnesia?

Cannot remember events leading up to the injury

12

How is intermediate long term memory maintained?

Increasing Ca2+ entry to presynaptic terminals, increases neurotransmitter release which strengthens the synapse

13

How is long term memory maintained?

Increase in neurotransmitter sites on presynaptic membrane
Increase in number of neurotransmitter vesicles stored and released
Increase in number of presynaptic terminals

14

What are the two main types of long term memory?

Declarative/ explicit - abstract memory
Procedural/Reflexive/ Implicit - acquired slowly through repetition

15

How does consolidation occur?

Selective strengthening of synaptic connections through repetition

16

In what diseases can memory become impaired?

Korsakoff's (chronic alcoholism)
Alzheimer's
