27
Q

What is affective memory?

A

To like something, love someone etc

28
Q

What is the major structural part of the brain involved in episodic memory?

A

Medial temporal lobes

29
Q

What is the major structural part of the brain involved in procedural memory?

A

Basal ganglia, cerebellum

30
Q

What is the major structural part of the brain involved in working memory? (spatial and phonological parts)

A

prefrontal cortex, for spatial

Broca’s/Wernicke’s for phonological

31
Q

What is habituation?

A

Diminished response following a stimuli

32
Q

What is sensitization?

A

Enhancement of a response by addition of another stimuli

33
Q

What is imprinting?

A

Bonding

34
Q

What is vicarious or latent non-associative memory?

A

Familiarity

Imitation

35
Q

What is acquisition in terms of memory?

A

Input

36
Q

Where does reconsolidation occur in the brain?

A

Hippocampus

37
Q

What does consolidation require?

A

Sleep

38
Q

What is memory extinction?

A

Loss of memory

39
Q

What occurs in the information holding period?

A

Recurrent circuitry

40
Q

What is the basis of memory formation?

A

Increased connection transmission between axons

41
Q

What is the receptor that is involved in memory?

A

NMDA receptors

42
Q

What is synaptic plasticity?

A

Ability of a neuron to adapt to new stimuli

43
Q

What are axon spines? What happens to them during learning?

A

Branches off of axons there synapses occur

Increase in number

44
Q

What are the two processes that take place to turn short term memory into long term?

A

Consolidation

Translocation

45
Q

Where is long term memory stored?

A

Throughout the cortex (codification)

46
Q

How do we retrieve memory?

A

Bring it back into short term memory

47
Q

What is potentiation?

A

Following a strong,
sustained stimulus or high frequency stimulus, the response to the
previously defined stimulus is greatly enhanced

48

A

Both
